Yea I didn't catch that cause its thrown into a thread of problems so I guess its better I broke it out for everyone to see incase everyone doesn't go through every thread. Thanks for the heads up!
Yea some peps have a life unlike me I have a lot of free time@ night . But its. A good thing to make it resurface many peps looking 4 it. ......pattyboy
OK I'm fairly computer literate but I just cant get this to work. I downloaded the file two separate times, unzipped and burned to two different CD media at 2x. Put the car in acc mode (keyless start), put the disc in and it takes a minute and tells me wrong update version.
Verified my disc has 2 files and 1 folder in its root.
I had similar problems and don't know if i have the answer.....i upgraded my cd burner with a DVD / cd burner and using Nero software and it works great ...try dowload using the ISO version.......
Didn't work for me... I currently have 2.201. I burned the .iso to a CD-R and it was recognized in the RER system as a DATA CD. But that was the extent of it. The TSB mentioned to follow the on-screen prompts, I didn't have any. Anyone else with a similar problem?
Possible flaws could include the data write speed, CD-R vs. other media & not going from v2.3 --> v2.3 --> v2.4
Check the other thread you posted in, I gave you directions to how to create a readable CD. Basically you need to "close" or "complete" the disk after the write and most burning software leaves it "open" so you can append data.
I keep trying; DVD-R, DVD+R, DVD+RW, DVD-RW...ughhh.
I have been using the .iso and I know a .iso is a compressed file that needs software to open fully, the system has this ability; correct? I mean I have to believe it does - it's working for everyone else
NO, the .iso file is a compressed bit image of the CD/DCD. The burner software decompresses the data and writes the CD/DVD. The radio can't make any sense of a .iso file, it needs to see the actual data files encoded within the .iso image.
Here's the details on how to burn the disk and update the radio.
Instructions:
Unzip the files to your Hard drive and burn them to a CD data disc:
1. For Version 2.402 - Name the CD to RER_2.402 when burning it. (Recommended)
Burn the CD at 2x speed for maximum reliability, and disable multisession (Add files later) on your burning software.
2. Root directory MUST contain only one folder and two files:
BECKER (folder)
CD_INFO.CDI
CONFIG.CDI
Start your car (Recommended), Load the CD in your MyGIG radio and the update will automatically start once the disc is recognized. Updating will take around 15 minutes.
I had to use nero lite, burning the files from the zip to a cd-r. Made sure it finalized the disk upon completion. That worked, showed as a data cd for about 10sec, then started the load.
An earlier attempt using a dvd-r failed, using the same burner and software. That disk would just hang a s a data disk.
mjw930, thanks. Great link with with detailed instructions. The first time I tried this I did exactly what these directions say, with the exception of renaming the disk as described; I just called it RER update. So in this case I would name the disc RER_2.402 (the example uses RER_9.713).
We will see what tomorrow brings.
BTW... you know what is ridiculous, that I even have to go through this. I asked my dealer to perform the upgrade and they refused. It shouldn't be this complicated. What gets me is the inconsistency in information floating around.
Some posts and other forums; Charger, Challenger, etc., say to use a CD-R and unzip files, others say it has to be a DVD and not a CD and others say the .iso is the preferred method as it works more smoothly as it is quicker than the zip file.
Paired the wife's iphone 4 with the 730N rer flawlessly. It took less than 5 minutes. (updated to 2.402 from 2.202)
I simply burned the disc with the iso image through the software that accompanied my 4 year old Toshiba laptop. (no issues with that either) I used a generic cd-r.
Yes...There is a certain sequence you have to follow in order to upgrade...some versions cannot jump to others without an incremental update. This website is your friend:

I'm a bit confused though. Why does the version go from 9.807 to 1.220? My '08 Grand Cherokee appears to be running 9.713 (which the dealer supposedly upgraded it to in August), should I be moving to 9.807 or to 2.402? Thanks!
