Hallo Everybody,

this is my firs post, although i have been reading a lot almost all the posts regarding the Denso nav installation on the trucks that did not came with from the factory.
long story short: i have a 2009 Tahoe LTZ, with Bose, Bluetooth and i bought of the ebay a unit 15940103 that is compatible with bose system, bluetooth etc.
Well after installation the blue scree came up saying Theft Lock.

But the Bluetooth worked with no problem before the dealer ship visit and in the seconds before the blue screen Theft Lock came up it did show on the left corner BOSE, not anymore!

I went to the dealer and they unlocked the unit but i have no sound now.
The navigation is tracking well(no sound tough)
they said is not compatible, i think he programmed wrong, it does not show BOSE anymore too
the Thaoe it came from was a 2007 LTZ.

Please i need help,
Thank You,

mg

Don't have this system but did you check the wiring? Could it be that the speakers disconnected?
