Hey everyone,

This is my first post in a long while... I have been trying to search for a particular problem I am having with my RHB unit and cannot find a thing on this error. When I power the unit on all is well. Music saved on the HDD plays just fine, radio works fine, and all seems good with the world. When I try to click over to the navigation portion of the unit, it doesn't do much. As soon as I press the NAV button, the unit just says "Guidance by Garmin" and stays stuck there. Tried turning Jeep off/on several times to no avail. Also doesn't matter how long it's on. I cannot for the life of me get this screen to go away.

Additional info:
This unit has the latest map / software updates from HERE - 2015 was the latest update I could purchase.

Any help would be appreciated. Will post pics when I get a chance.

Has anyone ever found a solution? This problem appears to be very common.

The NAV function suddenly does not work.

I have a 2015 Wrangler with the "RHB" radio. The SIRIUS component and AM and FM radio work well, but if I press the soft key for NAV, a splash screen appears, and never leaves until I exit NAV. The screen says "guidance by GARMIN". No Navigation features ever appear.

I have tried disconnecting and reconnecting the battery, the IOD fuse and the radio unit examining all external connections -- they look fine. No change.

Does anyone know how to enter the DIAGNOSTICS SCREEN for the 430N/RHB radio in the Jeep Sahara?

To answer to your issue I had also, i found a video on youtube very easy, but most importantly a comment from a guy inside that explain the following :

>for the video you type in youtube : Jeep Chrysler RHB 430N navigation boot loop repair
And then you read one of the comment below : It has worked perfectly for me, took 2 min.
"If you are experiencing the boot loop/ hanging at the nav. by garmin screen after a botched update, you probably won't have access to the 10-digit unit id number, and you won't be able to create the xml file that is required to download the gupdate.gcd file from chrysler/uconnect. The number along with a generated xml file seemed to be necessary to download a working update file (gupdate.gcd). I spent way to much time trying to find a workaround and I read a ton of posts on various forums.

Ultimately, I downloaded RHB-RBZ.50.01.01.iso from Download Now | MyGig RHB 50.01.01 Software Update. I was able to open the .iso image file in finder on my mac and I found the Garmin folder with gupdate.gcd inside. I copied that folder onto a freshly formatted usb drive and proceeded with the emergency install as shown in the video. Everything seems to be working now.

As has been mentioned already, the xml file is only needed if you are going through the official channels (chrysler/uconnect) for the update file.

brunalb - I think I did everything you described above, but was unable to get emergency to work, do I need the XML file for that? I have a 2013 Grand Cherokee with an RBH with 44.00.0, whenever I tried to do, it would give me the option for Emergency Update - Yes or Cancel, I would hit Yes and it wouldn't do anything. Any thoughts?

Familyofjeeps, I had the exact same issue. I am hesitant to do the full iso install as I would prefer not to brick my stereo, but the navigation was very handy so I wasn't burning up my phone when travelling.
I'm amazed that this has gone on for so long and Chrysler seems to not care at all. I have sent emails to FCA and made calls, but they are of zero help, and because we actually drive our vehicle, it's past the 60k warranty miles that I was told is required to get a fix. Very frustrating.
Seems to be another crap quality issue from Chrysler. They don't acknowledge it, won't accept responsibility, it must have never happened.

Another reason I bought the Lifetime Max Care service contract on both of mine.

Hi cjax920,

I'm sorry you haven't received the assistance you've been looking for. I'm not quite sure which 60K warranty you were told about, as it sounds like the concern you're experiencing would have been covered under your basic 3/36 factory warranty. However, we could certainly have a case specialist work with you and the dealership if you had an upcoming appointment scheduled to look into repair. If that's something you're interested in, please let me know! Send a PM with your VIN if we can help!

I have 2013 Trailhawk with RBH head unit - received official email offer from Chrysler/HERE/Garmin in Aug. Just got my NAV unit working again on Dec 7th BUT still with the OLD maps. The two-step software update hung and left me with the Nav by Garmin boot issue. Many calls to Garmin (their policy is not to give out software - later told me i had damaged a component); UConnect - even lead tech couldn't help; 100K miles so Chrysler wouldn't help - why is this even a warranty issue - I bought a product and it doesn't work.
Garmin finally offered $257 refund on my $395 refurbuised radio ($490 with install + tax). HERE gave me an RA to send maps back at my expense. Now with radio on current Garmin software rev I decided to call HERE today (Dec. 9th) to ask if they could change the radio ID# to match the just installed refurbuished radio. First they said they needed an emailed copy of my radio repair copy and new ID - when I asked how long it would take to get the ID switched they were non-commital.
I putting the map software back in the mail and cutting my losses at around $250 (after I get reimbursements back from HERE and Garmin) in 6-8 weeks; plus way too much time and aggravation. This was my 3rd Grand Cherokee and it will damned well be my last!
