Hi all, just signed up been a long time member from that other Tahoe forum. I am currently looking at a 2007 Escalade for sale on opposite sides of the countery so no way for me to check it out, and I already asked the dealer too many questions which they are hard to get a hold of. But How can I tell if it has Navigation or not, I see a large monitor in the dash but that sure doesn't mean anything; any sure way to tell? Thanks
