I recently got my tech2 one of the things i need to do in my 2004 H2 is to reprogram or vin relearn on a bose Lux amp i installed on my h2 . my truck came with the premiun amp i rewired the harnes to communicate with the new Lux amp and as expected after that i only get sound from the front passenger speaker as far as i had learn this is how the truck lets me know i need to reprogram the amp to my truck . do i need to download anything or is this something i can do with just the tech 2 ? thanks in advance .
