Does anyone know if the the radio wireing in an 07(non nav) will support the the head unit from an 06? I put the nav unit (from 06) it in and plugged everything in, then put battery cable on and started the vehicle. THe nav unit flashed the H3 logo for approx 5 seconds then goes to THEFT LOCK .? Can the dealer program this? THANKS FOR ANY REPLY!!!

 

radios are numbered for theft protection. it wont work if you bought it or stole it from a different car.
gotta have a dealer check it out

 

You are right,
dealer has to code unit to your vehicle.
