Does anyone know where the XM unit is and how to get to it??
07 H3X w/o Navigation. Thanks

 

Do a search on this website and you will find a plethora of information on this precise subject.
But it is behind the glove box.

 

It's actually pretty easy to get to.....when you remove the head unit it's to the right behind the glove box. You should be able to get to the XM wiring harness without having to remove the glove box.

 

I took the glove compartment off, but I did not see it back there.
I followed the "10 min ipod install", but I could not find it.

 

I have the Nav System and the XM which I had converted to SIRIUS - the installer pulled the entire silver face plate off which surrounds the radio, vents, etc and accessed the XM directly behind it (I believe it is refered to as the head unit). Mine wasn't behind the glove box. Hope that this helps.

 

Thanks for the info. Sounds like alot more than a 10 minute install. Where are the screws that hold the head unit located? Is this something I should be doing myself?

 

ragz12,
Sounds like no you should not be doing this. You have to remove the faceplate of the dash to access the head unit. The screws are right there staring at you.

Skoal,
Thanks, this is exactly what I needed. It looks like the XM unit is below the radio. If that is the case then all I need to do is remove the bezel to install the Nexus. Wish me luck.

 

The Tech used what equated to be dental tools or small picks to pull the top corners away first and then the lower corners. I can best describe them as a snap/compression fitting. I was nervous even watching him pull the face plate off, but it is probably something that you can do with the right tools. Just make sure that you work them into the dash between the silver face plate and black plastic just under the vents and pull straight back......underneath the plate there may be some small screws that hold the guts of the unit in.

 

So I guess that the 07 xm box is behind the radio and not the glove box. Bummer[]
