Just thought I would share my experience with the install of the GMX 550 Lockpick into a 2008 Tahoe with NAV and DVD. I would have to say that the installation was fairly simple. The connections are definitely keyed to ensure nothing is plugged into the wrong location.
The OEM has additional connections in the back but you simply leave them alone and plug in the three that comes with the lockpick harness. I will have to say that the video from coastaletech regarding the installation that I found was a little misleading. From the video it appears that the lockpick can simple be installed and fit right behind the OEM radio. I found that to be impossible because the 550 lockpick is simple to big to be installed there (in my humble opinion).
I installed the lockpick underneath the cupholder in the truck. The cupholder came out pretty easily. It has the same type of connections as the material around the factory radio. I was able to run the wires for the lockpick down the left side behind the radio and towards the cupholder. It will be a tight fit because the wires and "just" long enough. Also, I ran the USB and IPOD cable down the same path but popped them out the bottom of the center console by the drivers side. I will probably do more with the IPOD and USB cables later but that's what I've done for now.
Of course, I tested before putting everything back together but it worked instantly. I was going to attempt to install a Parrot bluetooth kit with the system but I have been reading threads where you can use the 09 Escalade Bluetooth/Onstar module to get bluetooth in the 2008 Tahoe. I will let you know how that goes.
