You will need the gps antenna part #15201798 and you will need to get the connector kit with the vss wire and the two wires that connect the Onstar box to the nav radio. The kit has two connectors included, one plugs into the nav radio with a single vss wire attached and the other connector plugs into the Onstar box with two wires which have micro connectors on the ends that install into the factory harness connector that also plugs into the nav radio. The kit comes from JP Customs in Texas and is $44 including shipping. The gps antennas are available on eBay for $55-65 usually. Also see my previous install post here http://www.tahoeforum.com/showthread.php?t=460

You WILL have to have a dealer flash the nav radio after you install it (unless it was new in the box from gm) as it will be locked and since all of the sound functions in the 07's goes thru the audio system you will have no sounds, nada nothing until you have the radio flashed.

U R Da Best

Thank U Very Much ,,,so I Am Pretty Much Set,,,,is There A Specific Name Or Part Number For The Vss Connector From Jp Customs,,,i Will Go Online And Order It,,,,and I See You Have The Same Set Up I Want To Install,,,,do U Have Any Problems With It,,,does It Run Smoothly With All Of The Factory Functions Working Correcty,,,,i Heard Some People Say ,,,the Horn Ddoesnt Work Or Sound For Signal,,,did U Experience This ,,,and /or Get It Fixed Or Just Lived With It

You won't be able to order the kit online as they don't show it. Just call Brian at JP Customs and tell him you are installing a factory nav unit and need the kit with the two connectors, he will know exactly what you want. As I said before until the nav radio gets flashed at the dealer you will have no sounds from anything not even the click from the turn signals. Everything works fine after the flash and I love this unit and will never have another new vehicle without a factory nav unit!

Yeah I Am Definatly Listening To You And What U Recomend,,,just So I Dont Get Robbed At The Dealership,,,,,how Long Will It Take To Program The Head Unit,,,because I Know They Charge By The Hour

If the tech knows what he is doing then it will take 15-20 minutes and they will probably charge you for 1 hour.

Here are the tech tool computer codes they used on my Yukon without the rear dvd
