Hello,
I have a 2018 Mirage G4 automatic that I am attempting to upgrade to an aftermarket radio, amp and sub. The radio I want to install is a Boss audio BV765B. When I installed everything, the system works fine, only issue is that the cars service engine soon light comes on and the car won't go into gear. I checked the code that came up, saying it was a transmission sensor error. I did not connect the backup camera or the parking brake wire to enable the DVD/media. I'm thinking that it has to do with the backup camera not being connected. Thoughts?
Thanks in advance.
