RHB 2013 - Navigation stuck at "Guidance by Garmin"

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.
