There is one thing that i recall from a few years back & i assume that it still applies
If you are a smart phone user & are registered
with Uconnect Advantage or Uconnect Access, which ever name that they are using now.
You can shut your phone OFF & still push the Assist button to call the the Ram Assist office in Auburn Hills, MI, using the vehicles SDAR, ID Cellular
The 911 button should always work, whether your are a registered Uconnect user or not, but i am not positive about that
Our Ram & most of the other Dodge/Chrysler/Jeep vehicles that have those two buttons on their mirror, have a built in VIN assigned phone interface built into the vehicle.
You don't even need a cell phone within miles of your location to use the vehicle phone
For those 4th Generation Rams, etc, that are having radio issues, including your buttons on the steering wheel.
If you are curious about why your radio does not function correctly, you may find the answer below
Performing these functions may fix or brick
