I have an 04 EXT that has navigation rear dvd and bose. I would like to replace my stock navigation with a Pioneer avic-z2 that i currently have in another vehicle but i have a couple of questions about the stock navigation. First where is the GPS antenna located in the stock navigation? Is it inside the unit itself or located somewhere in the vehicle? If its not integrated into the stock navi does anyone know if it will fit or can be adapted to a pioneer navigation so that i dont have to install the antenna that came with the pioneer unit? Can anyone tell me which adapters i will need to buy in order to keep all stock functions working in my vehicle using an aftermarket navigation such as steering wheel controls, bose system xm ect. Finally will any features be lost by adding an after market navigation (are there some things they just do not make adapters for) After installing the aftermarket navigation i would like to sell the stock navigation can anyone tell me what models my stock navigation is compatible with like other escalades or possibly hummers or chevy vehicles?

The antenna is on the roof in the front. The wire from it plugs into the rear of the stock nav bose unit

I put a pioneer avic d1 in a few yrs back i used a Pac os2bose module to keep the factory amps and bose speakers I also bought a PAC module to control my steering wheel controls

you actually have to cut the gps antenna wire and cut the pioneer gps antenna wire too, and put the end from the pioneer on the factory antenna, is not that hard to do, if i was you i would just install the antenna under the dash, it works fine, i have even seen in dome gm tha antenna coming installed in a little plate under the dash, i am a installer and have done this many time even in my own vehicle, it works fine.

I'm an installer too. I personally would not recommend cutting the gps antenna. You will not get an optimal signal doing that. It may appear to workbut could be a problem in the future.

PAC and Peripheral both make the interface components you will need for the Class II data bus (and amp communication) and to utilize the factory steering wheel controls.
