How much does it cost to put a GM navigation system in a 2007 Chevy Silverado?

[lsurocks122593]

The truck has the standard LTZ radio, but I want to put in a navigation. About how much would this cost?
I only want the official GM one and nothing else. What will the total cost for everything be?

Dude, you should just buy a Garmin. Cheaper and don't have to pay a monthly fee which I'm pretty sure GM charges.

more than you would get for selling your left nut. Best bet is to get an aftermarket nav system from Tom Tom or Garmin. It will be portable, better, and probably 1/4 the price

or any of teh Garmin Nuvi's are great as well

To answer your question though I would bet on around $1,200 to $1,500 to install it aftertermarket
