Adding Nav
Have a 2015 and want to add Nav again. I say again because I ordered the HMI from a vendor and while it worked perfectly it clashed with my onstar system giving me the red light and error not receiving onstar, whenever I called onstar they could not determine my location. Called the vendor and they were not able to fix it so I returned the HMI. Has anyone installed the Nav hmi and been able to use onstar also. Different vendors? or is the onstar module mated to the hmi.
