Does anyone know what you have to tell the dealership to get them to unlock a factory nav system that I installed. 2 diff. dealers wont do it for me.

Also for adding nav to your H2 be careful. In 04 gm used two diff. Bose amps. LUX and Non LUX. YOu must have a specific part number for it to work. Delphi tech gave me these unit #'s for factory nav systems

LUX unit: 15204335 and 15118439
Non Lux :15108421 and 15120706

find a technician at any gm dealer and slip him 50 bucks. i dont kmow what kind of dealers you guys deal with but i unlock radios all the time.i guess your dealers don't whant to build a good customer database.
