I do not have the NAV unit in my Z71. The word Bose is written on my front speakers and I do have the rear DVD player.

If I wanted to replace my radio with a NAV unit which one do I want?

Also, will it show video if I put in abackup camera?

I looked in my glove box at the sticker and it has all kinds of numbers on it. How do I determine if I have the Y1 or Y2 unit?

Thanks

Chris
