Hi to all...I did search but... new to me 07 Hummer with D3. Everything works but I want to add the BT200 for the phone link. It says a reset is necessary. I have the manual and have read the search on password. Can I go to the 1-2-3 password set and tell if it has been set or not AND still back out without lockup?? I would hate to screw this up. No idea if the previous owner set password...nothing written in the manual.
Thanks
