Question regarding the Denali 07

[yukongt]

I own a 2007 Denali and I would like help on two issues:
1. I would like to replace my radio player with the OEM navigation system is that possible?
2. If I want to change my tires/wheels to the optional 20" Denali wheels, do I need to recalibrate the settings? In other words is it a hassle to change them? If so what is involved.

Thanks in advance.

I would ask the same questions at http://www.tahoeforum.com/

The board seems to go down a lot but I believe you've find the right folks there.

Just an update I found the answer to my first question at:

If anyone can help with the second question I would be most grateful thanks

It all depends on what tires you go with. Here is a site where you can input your stock tire size and input your upgraded tires and see what the difference is. http://www.1010tires.com/TireSizeCalculator.asp
If it is slight you might not have to recalibrate your speedometer. If you really need to recalibrate your dealer can do it for a hefty fee, or get a programmer, or get a custom tune and get more power and recalibrate your speedo at the same time.
