2015 Terrain Infotainment issue


I own a 2015 Terrain that had the infotainment system screen go black. Have tried fuses, etc. After a trip to the dealer I'm told that the onstar module has gone bad and until it's replaced the radio/gps/bluetooth/backup camera will not work. Will removing the onstar module solve the problem? I don't use onstar so it's not like I would be missing anything. Seems crazy that this would shut everything down. I have found some places that will sell a new onstar module for less that what the dealer wants and an independent guy with a programmer but hate to spend the money if it's an easier fix. I've also considered the aftermarket route. Any advice would be appreciated.

Is your radio dead also? Our screen and radio just died. Have tried fuses and disconnecting battery. Have not made a trip to dealer. Research seems to indicate the most common cause is the radio. My On star still appears to work although we do not pay for the service.

I am trying decide if it is even worth a trip to dealer or should I purchase an aftermarket radio and skip a trip to the dealer?

gannon33 - did you get the issue resolved? I've had my 2015 Terrain at the dealership twice. After researching the part number they say will fix the problem, it doesn't fit my vehicle! So frustrated! The only thing that works is the heat/ac. Screen is blank, no radio or back-up camera function.
