Nav Radio Help

Hey I'm new here to the forum and was wondering if anyone would know where I can find a factory nav radio for my tahoe? Mine came with the 6 cd changer and I kinda want to upgrade. A friend of mine bought one on ebay and had it reprogramed at the dealer in our town. So If you know where I can get one please let me know.

I think you answered your own question, welcome and good job.

You can find them all over the internet. Ebay is the best and cheapest place to find them like you said.

make sure they come with a gps antenna...without it, the nav is useless

Thanx i'll keep lookin

Just upgraded mine. My CD changer crapped on me and the dealer could only put a replacement so I got one from Ebay with GPS antenna & a map disc.

so u got the nav sys in your truck now? awsome! I still cant find any and when I do they want this outrageous price for them. Guess I'll keep on lookin...
