730N RHR - Lost Nav - Diagnostic Help?

Lost navigation on 2011 Summit built in Feb '11 with 730N (RHR). Car has 20k miles without problems except losing satelite radio presets after switching driver memory.

Now: (1) blue tooth phone link continues to try, without success, to load phone book; (2) navigation says maps not on HDD - reload maps; (3) system info screen will not show total HDD capacity, capacity left, or capacity used - only shows dashed lines in all three boxes on screen.

My conclusion: HDD is mechanically defective now, or some part of software is locked up.

Does anyone know how I can diagnose this failure?

I don't have any experience with a good dealer, or know how to locate one even though I am willing to travel. I'm afraid of them doing a bad job of R & R the radio unit or not knowing how to analyze the problem. I thought the dealer service departments had a 5 star rating system, but have not been able to find dealers by ratings. I'm in the Albuquerque, NM area and we have two dealers, but they are not very confidence inspiring.

I think I can do an OK job of R & R the unit, but I'm not sure of how to remove the HDD once the unit is removed.

My ideal fix would be:
1) Accurately diagnose the HDD as the problem.
2) Remove audio unit myself.
3) Remove HDD from unit myself.
4) Purchase (even though car is on warranty) new HDD unit.
5) Have a computer shop transfer all data from old to new HDD.
6) Reinstall HDD and audio unit myself.
7) Ascertain that all is fixed and functions.
8) Update software/firmware myself (car probably has earliest version). I think I can follow good instructions.
9) Hopefully lost presets, or any other problems would be gone.

I would appreciate ANY help, or critique of my situation or my reasoning.

Thanks in advance.

The HDD is tied to the radio mother board (encryption key). It does you no good to try to save or transfer your data, it will get overwritten and you will have to start from scratch anyway. You probably will also need probes and board programming know how to reset the motherboard for the new HDD and load the boot code on the HDD if needed. It is unlikely that you could get a HDD rated for the auto environment anyway. Those you get retail won't handle the temperature extremes, let alone the vibration.

Your best bet probably is to have the radio replaced, or try a firmware update, the instructions are in another thread here. You can also try to do a radio reset via the engineering menu, the instructions are in a thread around here somewhere. You could pull and reset the radio fuse. But if you are having so much trouble there is probably something wrong in the radio, and not necessarily the HDD.

It is fairly straight forward to remove and replace a radio.

Thanks ColdCase:

You helped me a lot by eliminating some blind alleys. I think trying your suggestions in the following order may be the least troublesome:

1) Remove and reset radio fuse. I know where the fuse is and how to remove it, but am not sure what the reset process is. I will look for the thread here because I think I saw it in this section.

2) Reset radio unit to factory defaults from engineering menu. I also saw instructions for this here.

3) Attempt to update software version. I noticed that some had troubles and some did not, but I figure at this point I can't do any harm.

4) Replace the whole unit. I would like to do this myself, but need a dealer to provide the new unit under warranty. My experience is that they won't honor the warrantee unless they do the R & R. In that case, I need to figure out how to find a dealer I trust not to mar the dash leather, or break the internal clips, or leave out mounting screws. I may be able to remove the bezel myself and let the dealer R & R the unit.

Thanks for responding,

I just had my radio replaced due to loss of USB connectivity (USB sticks, iPhone, iPod, etc.) Also could no longer play music through bluetooth on iPhone, but calls still worked. Anyway the point of my story is that my dealer's service department blows, but any dealer should be able to replace the radio without you noticing it (as mine was). It's incredibly simple. I've pulled mine at least 6 times. If your dealer screws that up you should never go to them for anything else, ever...

Thanks *sox*:

I'm going to do the three software steps first, but if I need to R&R the radio unit I'd appreciate your help. However, I don't understand the nature of the help you could provide.

I see you're in Switzerland. Would you be able to drop ship me a new radio under my warranty? Would I then need to ship my old unit to Switzerland? Also, what do you mean by "generating a new hdd?" It seems to me the new radio would be ready to go?

Appreciate any explanations you are able to provide.

hi

mabe i have understand wrong, but you write you have a "broken" hdd, you have no space, no navigation etc.., rigth?

then you need only a new hdd!

when the hdd are good go with this step first.

you can not do 3 step.......we have only 1 update!


- make in the e-menu a factory restore
- after restart from the system install the 2.120 again.

when the update are finish close the car for 2 min. for shutt down the canbus.

then go and test it......and giv feedback!

Didn't mean to misslead you *sox*:

I have the symptoms described above that make me suspect hdd MAY be bad, but don't know yet. I plan to do what you suggested first because it is easier than jumping to the assumption that hardware is bad. Here are the three steps I plan to do (when the wife quits driving the car):

1) Reset radio by removing and replacing the fuse. I understand this would be like rebooting a computer.

2) Reset radio to factory specs through the "engineering screen" as you suggested. Maybe this would correct any troublesome settings.

3) Install latest firmware/software(?) 2.12 update. I have an earlier version as my car was built in February '11. I still need to locate this file to download it to my computer.

After these three software steps, then I will assume it is a hdd issue and go to the dealer for a new unit under warrantee.

If I'm missunderstanding anything please correct me.

ok *sox*:

I'll work with what I know now and keep you posted. Will also take pics when I do it. Pics are a good idea. I didn't think of it.

I got the 2.12 downloaded to my computer. Need to go buy the DVD now for burning.

Thanks

Update on Nav (RHR) Problems:

First here are my original symptons with screen shots. Navigation not available, HDD info not available, system info shows navigation not found, phone book unable to load into HDD (first four pictures).

Using advice from this thread (thank you all) I did the following.

1) Disconnected the vehicle battery and let sit ten minutes to restart vehicle Can-bus system and reset radio. This step made no difference to original symtoms.

2) Disconnected radio only by removing green fuse M12 to see if radio reset without Can-bus system reset made any difference. This step also made no difference.

3) Went into Engineering Menu (press up and down seek and menu bottons at same time) to reset to factory defaults. The screen (fifth picture) said "restoring defaults" but never showed any progress or finish. I let it run for over 20 minutes and decided to exit, but could not. The radio controls were inoperable. The car was running, so I put it in reverse and the back up camera came up. After that the radio returned to the home screen, out of the Engineering Menu. Again, no difference was detected. Original behavior remained the same.

4) Made both a DVD and a USB with the 2.12 operating system and inserted the USB first from the system menu. The USB kept flashing, but there was no indication the radio was reading it. After about 15 minutes, I removed it and installed one MP3 music file on it, as I read here someplace. Same result, radio not reading USB stick.

Even though I had the DVD, I was afraid to insert it because I read about others who had the radio freeze all controls and they could not remove the DVD. So again, I was unable to fix the problem.

5) Removed the radio unit itself to check the input wire plugs for looseness. No looseness detected. Noticed that the HDD hatch was on the bottom of the radio box and opened that to check for loose wire conections. None were detected.

Took the HDD to a local computer shop to see if HDD was bad and whether data could be transferred to new HDD. Amazingly, they had a used HDD on hand that was a different brand (Hitachi not Samsung) but appeared to be the same in specs and size. However, when the technician hooked my drive to his computer he could see the folders but not access the data. He could not tell me if the reason for no access was a bad HDD or a different file format that his computer would not recognize. I'm not positive about this attempt because I'm not computer savvy and the young man was talking fast and was hard for me to understand.

Put everything back together, leaving the bezel loose to make it easier for a dealer technician to remove radio without breaking the tabs or marring the dash leather. After all this R&R hassle, no difference was made in the original symptoms.

5) Looks like it's going to the dealer for warrantee work. I don't have ANY confidence in my two local dealer service departments so I am now working with the service department where I bought the car (500 plus miles away). I sent them the four photos of the screens that show the problems. My hope is that they can determine whether the radio needs replacement or if they can correct the problem. If the radio must be replaced I would like them to order it in advance so I don't have to make two round trips there and back.

If any of you have any advice or help out there, I'd appreciate it.

Boy are you going through a lot of work for something that should be taken care of under warranty.

Check this guy out. His information shows descriptions of exactly what you are experiencing. I have communicated with him on other media center issues and he is knowledgeable, honest and inexpensive.

http://www.ebay.com/itm/MYGIG-RER-L...4001938?pt=BI_Blank_Media&hash=item4aa877c712

Go to the very bottom - item 1: Corrupt 730N HDD and how to contact him regarding what is needed to fix.

Best luck.

For the RHR dont exist a HDD fix and in 50% this not work anyway, i have make many test etc... and the finaly sucess are ever a new generatet / parttioned hdd

So what harm is there in the OP asking the question of the contact I listed?

If it were me, I would take the GC back to the dealer and let them fix it.

However, they may take exception to dismantling the dash and radio - including removing the HDD. Personally, I would never inform the dealer that was done - can you say "warranty voided"?

The situation is likely either corrupted software or hardware. Either way, let the dealer fix it under warranty. A replacement radio is $2,000 so this is not small change we are dealing with here.

I understand the OP does not trust his local dealers for some reason, but that is his decision.

To Justal13:

Thanks for the tip. I followed the link and read the listing on e-bay. So far, he does not discuss or offer software on the 730n (RHR), only the (RER). I made a note of his ad so I can find it later if needed.

Looks to me like *sox*'s solution is the best way to go at this time. Now that I've done the R&R on the radio once, I don't have any problem with doing it again to switch the hdd. After it's done, the dealer won't be able to tell its been apart.

To Marco:

I responded to your PM with another.
 
#24 ·
Update: Thank you *sox*

Thanks to Marco I received a new hdd for my 730N (RHR). Plan to put it in early next week after the wife gets done using "her" car.

I will share the results after I get the hdd and software installed.

Sox rocks!!!

He diagnosed my problem of lost navigation perfectly. I switched HDD drives and the navigation came back without updating the operating system which was 1.908.

I then updated to 2.120 by DVD. Tried to do it with USB, but was unable to get the unit to read the update file. It would read a music file but not the update. Tried with a different USB, but it didn't work either. That's when I went to the DVD and it worked perfectly. Took about an hour and twenty minutes to update.

After the update I checked a few things and all seemed to function OK. Will check out other details as time permits. I took a few pictures to help document the process.

Thanks all for your input and especially Marco for his help. I really appreciate it.

Vic
