I have a 2013 Challenger SRT8 CORE. It didn't have Homelink. I bought and installed the OEM headliner wiring harness part# 68079665AB and the Homelink Module part# 1HT94XDVAA. The Homelink and compass are listed as avaliable options on the 2013 CORE. I went to the dealer to get them added to my VIN and activated with the StarScan tool. After they pulled up my Vin , these options don't exist for my car and they said they cannot add them. Can anybody help me with this?
