I'm thinking about getting a new head unit for my car. I'm looking to get something double din, with nav and iPod/iPhone integration. Bluetooth would also be a bonus. (I do have a Pioneer 2300DVD right now).
Anyways, my main question is, would I be able to tap into the XM antenna on the roof and use that as my gps antenna?

This is one head unit I'm considering:

Feel free to throw different choices out there too.

 

Pretty sure you still need a tuner specific to the deck but u can use the antenna on top of the car instead of the one that comes with the kit.

 

in short. no. the xm box is under the rear deck cover. pain in the ass to get to. it's the brown connector on the passenger side of the box.

Alright, then my next question; how to you take it off? Is it adhesive? And does anyone know if there is a wire running to it through the roof?

 

i honetly dont know but if you take it off there will be a hole in the roof

 

Urg. I just want to find a nice and easy play to put the nav receiver.

 

do you have the shark fin or the mini one

 

The mini one.

Edit: another question. Would the 2300dvd I have now use the same harness that plugs into the back of the unit as the X40BT?

 

its very possible but not guaranteed double check before you use it

 

Of course. I just got my fingers crossed. It'll make it alot easier.
