hello,

First off I bought a nav radio (denso) to put in my tahoe. I installed it today and it turned on and worked. It did not display the theft lock screen. Is that ok?

I hooked it up and everything appears to be working fine all the wheel controls work and stuff. One thing is that i can not set the time. I do not have the map disc in there is this why?

I dont have a bose system and I bought a unit that needed it. instead of going through the dealership Im going to get a local stereo place to do it. Is that ok?

also how can i add a rear backup camera everytime i put the car in reverse it shows a black screen.

Other concerns: My turning lights don't emit sound i guess i need the amp. Also do i need to get something to install the camera? I dont think i have the module. Do i have to reprogram my nav through the dealership even though it was unlocked. any other connections i have to do? When i installed it I only plug the two pins that were in the factory radio. I have a 2009 lt chevy tahoe.

Thanks,
