Bought the programmer mainly to adjust speedo and tire size. The instruction manual says you must remove fuses to Onstar; and gave locations for 2001-2002 and 2003-2005. This is not the same for 2007. I've been pulling fuses and it doesn't drop out. Any ideas?
Thanks, Shep

I don't know Hypertech works, but I bought a Predator and didn't have to pull any fuses for the On-Star. I only had to pull 3 fuses and they were all for the radio.

Pulled the info fuse, plus those to radio and anything else that looked possible; light didn't go out. Great idea tho, will put a piece of aluminum foil over it, maybe an old goldpan or such. Never would of thought of that! You guys are great!:grd:

Does the new Onstar antenna unscrew like the 04/05 trucks? Might be an option for a no service signal if it does.
