Did you ever get this problem solved?

that is an interesting problem most likely its an issue with the stock amp. The denalis etc may have a different amplifier system vs what your truck has. Ill talk to some of my chevy guys if you are still having the problem and see if they can pull anything up.

Any additional info you could give would be great. Also, does anyone know where to obtain the gps antenna that is needed?

You'll need a GMC amp, the stock bose one you have won't work. I have had the same problem with my Tahoe. Check out the above thread.

jeepguy44, what year was your tahoe? Did you have the RDS 6 disk changer already in it? How much does the upgrade for the amp cost? Thanks for the info!
