When I began looking into this, there wasn't much info out there and most of it was wrong. So I took the plunge and bought a factory nav and it worked out great.
The Nav unit I used was GM Part#25817032, I believe this is the only unit capable of fitting our dash, that gm offers.
It is plug and play, there is no need to change any wires around or do anything else wiring related.
You will need to have the radio VIN-Unlocked, which will cost $35ish at a dealer, or any one local with a tech2.
You will need to add a gps antenna $35 shipped or if you can wait only $17 shipped from china. You just plug it in and then mount the antenna about anywhere in the dash, so long as it is close to the top.
You will need a factory nav disk, but 99% of the used radios will have it in it. The dvd tray is somewhat hard to get to, so most won't ever take it out. But, if for some reason you need one, pretty much all gm nav disk are interchangeable, so just find the most current one in your price range and buy it.
The factory navigation unit does have an amplifier built into it I saw where many people claimed you needed bose to use it, other wise the speakers would be very quiet. But, I plugged it in and it was just as loud as the standard cd player.
