I’m with you. Own a new Ram 1500 Laramie with the 12” screen. My issue started on November 1st of the year (2019). My system reboots every 90 seconds, without fail. Could set a clock to it. I lose my radio, Nav, backup camera, Bluetooth, cross path detection and rear radar. Opened a case with RAM customer care and the reply is the same BS song and dance routine other guys have reported getting for over a year on these new rams. Had I known about this prior to purchase, I wouldn’t have even considered this truck.
Did you open a case with Ram to track the issue?
Part of the issue is that there are THREE PARTIES that deal with this. Call RAM, and they refer to Chrysler Uconnect (who deals with the screens/head units themselves), issue with Assist/SOS - call SiriusXM/Guardian.
Hit my SOS by accident one night, rang endlessly with no one picking up (thank GOD it wasn't a true emergency) - ended up having to disconnect the battery the end the SOS call - even shutting off and locking the door didn't shut it off.
I called Sirius and told them to SHUT DOWN THE SERVICE (even though I was only 5 days into my "free year).
A Uconnect screen that re-boots every 90 seconds is a HUGE ISSUE - and I would be sitting at a dealer until the service manager called RAM and got a new one coming in, or called the COPS to drag me off. Since the screen affects SO MANY FUNCTIONS of the truck (many being safety related) - I would get them to WRITE IT UP - and KEEP BRINGING IT BACK - then head over to a LEMON LAW LAWYER and get them involved.
As far as the NAV itself goes - with 4QTR 2017 maps (and we're now in 4QTR 2019) it's USELESS in my estimation. I use GOOGLE MAPS in CarPlay anyways. Touch the screen, tell it what your looking for (including contact addresses on your phone), it pulls it up - PRESS GO.
Now - in other threads - RAM said December 2019 for a "software update" that's supposed to fix many issues.
Lee Iacocca wouldn't put up with this crap...
