i have a 02 tahoe lt with onstar that i dont care for... can i buy the regular 13 dollar harness to put in a h/u and just cancel off the onstart.. or do i HAVE TO keep the onstart working?
it would be best to keep the onstar. in my car i had to go with the more expensive harness otherwise i would lose other features like the remote start.
no. my car came fully loaded and i needed the better harness or i would have lost a bunch of features. the easiest way to find out would be to call best buy or even better you could call the local dealer to find out what harness you would need
