Just installed a Pioneer DEH-X9600BHS last night. Not bad but coming from a full 2 din Navi system I'm disappointed.
Will probably bite the bullet soon and join the dash cutters club.

Also for anyone interested in this HU, the radio door hits the volume knob when closing. I had to modify the radio brackets to have the radio sit a little further back to avoid this as I do not always want to remove the radio when I park. In doing this the radio face cant drop completely down although I can still load CD's and remove the faceplate.

I'm even thinking of returning the radio and getting a Kenwood unit.

As far as audio quality, it sounds pretty good with the stock speakers. My main reason for upgrading was bluetooth streaming.

Also did a little sizing for my amps that will be going in real soon...

Here are some pics...

 

How much did you have to move the holes back?
Thanks for the help.

 

I did not measure unfortunately but ended up making the existing holes longer so I could slide it back more.
Its about a quarter of a inch of extra clearance that is needed.
I bought some new brackets since I hacked up the originals. When I install those I'll take some pics.

 

Thanks friend.
