I ended up going with a Sony WX-GT90BT. I don't especially like the touch screen look in the SVX [to modern], or the Single DIN look which to me looks like something is missing in the space. This one seemed to fit the bill and had a more classic look than the Pioneer, plus it has a option to add XM radio.
Like anything on the internet there was both good and bad reviews, most of the negatives pointed out the display screen which doesn't bother me. I'll report back on fitment and functionality, and post some photos after it arrives.

Also I will be putting my WRX 6 Disc changer with the "svxdc" wiring adapter up for sale after I have removed it and installed the new unit. Anyone interested can pm me.
