What a great forum/thread. I have read the entire thread a couple of times, and I noticed that there are some updates to the the JP Customs harness Kit as well as the Lockpick from coastaltech GMX320. I thought i would share the info and have ask some questions.
So This is a Yukon 07 with Bose & 6 CD changer. I have replaced my Radio with OEM Nav. I bought the kit form ebay for 1200 (NAV part #15940102, Antenna #15201798, MAP DVD #15807780 v1.10). My final objective is to get a front and rear camera installed and a bluetooth kit.
I have the following questions/issues:
1) the easy one first, does this unit support or have XM Radio? if so, how to enable it or use it?
2) I went to the dealer to get the unit programmed, after being asked me a million questions and trying to tell me it wont work, the tech started working on it and then came to tell me that its giving him 2 codes (sounded like error codes), one for VSS not present and the other for the GPS module not present - is this normal?. I told him that is fine as i'm getting the VSS installed, he insisted that there is an additional GPS module. When I tested the unit after leaving the dealer, the GPS was not working, no signal on a clear day. I drove from Boston to NYC and on the way the GPS was started getting a signal and started working, and then it would not work - no signal. I was able to input a destination while driving, but was not able to get the voice prompted directions. Is all this related to the VSS wire? or is the Unit I bought faulty and GPS receiver not functioning propoerly? other functionality seems to work fine. (I also asked the dealer to enable the camera which he did athough i have installed it as or yet).
On the VSS and backup camera I have 2 options/questions:
a) Order the JPCustom harness so that I can test the GPS and ensure everything works well. Apparently this newer harness comes with an RCA input for the rear view camera install (makes it much easier - still need power for cam though). Also, the person mentioned that you can buy the RCA cable seprately and install it on older harnesses. They currently don't have it in stock but should be available shortly
OR
b) Use the lockpick GMX320, I was told by coastaletech that I don't need to install a VSS because the new lockpick GMX320 has that sensor already. There instalation manual states:"ALSO, SO, IF YOU HAVE ADDED A NAVIGATION RADIO TO A NON-NAV VEHICLE YOU MAY OMMIT THE COMPLICATED INSTALLATION OF VEHICLE SPEED SIGNALS NORMALLY NECESSARY FOR THE PROPER INSTALLATION PROCESS. THE GMX-320 WILL PROPERLY PROVIDE THE NECESSARY INFORMATION FOR YOUR UPGRADED RADIO." Has anyone tried the GMX320 without the VSS harness, and does it work properly as stated? Although, option B is much more expensive, it provides the flexibility for 2 cameras and an easy installation of bluetooth kit. 5) How do I enable voice activated commands? Would the GMX320 have that or do i need another harness? 6) I'm looking to buy and install a bluetooth - any experiences? (this would be a early next year project) Thanks in advance for your feedback.

Thanks to all you helped with this post. I got my Nav in my Yukon just fine. I ordered some of the plugs from JP Customs but have to tell all, I have been mis-led and lied to. I ordered the Nav kit with back-up camera plug, just in case I wanted to install that too, since it was an extra $5.00 with the order. The man told me the Onstar plug was on back order, but would be sent out as soon as they got them in to fill all existing orders, some time in November but most likely in early December. That was told to me twice, but it never showed up. I called and email them just today, now, its another $35.00, because they can I guess. If anyone knows where I can get the plug, I would love to know. I trusted these folks and paid for the plug so I could get my unit up and running thinking they would honnor their word, but got screwed in the end. Its not right, but I guess that's how they want to do business!
Any way, thanks to all who help me, and be cafefull if you buy from JP Customs!

When you say the volume, do you mean the radio or the amp? Did you use a used unit from another car? If so, you will most likely need to take it to the dealer and have them hook up and program it for you.

Hello to all,
I just finished installing the nav unit, antenna and vss wire in my new silverado. I have the theftlock activated screen. My question is does everyone who has had it programmed at the dealer agree with the instuctions in post #1 and pasted below exactly. just checking before i go to the delaer on Monday.
The unit will show a blue screen and the words THEFTLOCK, don't be alarmed this is good.
Now you'll have to take it to the dealer or have access to a Tech-2 device and TIS programs to accomplish the programming/learning procedure.
With Tech-2 connected to the vehicle go to the Service Programming mode and select "get vehicle information” and follow the prompts to download the module info into Tech-2.
Now disconnect Tech-2 and connect it to the Techline TIS computer and enter SPS menu select "radio” and then it will ask you a few questions regarding the radio, amp rear camera, etc, the only tricky one is make sure to select "w/o Y91 option the 2 times it asks and also select "region 1 NTSC” when you get to that screen; when done in the menu download the programming and then connect Tech-2 back up and install the software when done turn ignition off , unplug Tech-2 and wait at least 30 seconds to turn the key back on and your done.

I finally broke down and installed my Nav unit in my 07 Avalanche, I can tell you it was alot more work than I anticipated. Got my VSS kit from JP Customs, had it in one day, (They are in Houston so it was pretty quick for me). I do want to let folks know about the problem I had with trying to hook up the voice option. it took me an hour to go back and finnally take it out. I did exactly as the past post have talked about pin 4 to pin 5 and vice versa from the onstar to the unit. Some how some way the truck went dead when I did this procedure, I mean dead no lights, would not start. ZX1100F1 first of all thanks for all the information, I'm sure there are alot of folks out there that have used this info, do you have any idea how this may of happened or if I have do something wrong.
Second question is how can I tell if my unit has a Nav disk in it, I purchased it from a guy here in town and he couldn't remember if the disk was in it or not, I'm scheduled to have it Tech 2 on Tuesday. Thanks again to all that posted on this thread.
--Mike-- 07 Texas Avalanche and lovin it.

Does anyone know if there is a way to bypass factory nav/dvd system to where you can watch dvd while driving, I dont want to watch it myself but I want to put 10.2's in the head rest and I would like to run it off of the factory head unit (if this is possible) so my kids can watch did not want to have to buy an aftermarket head unit like Z1 or Z2 I did not want to lose my sterring wheel options and plus be out that much more money.
