I currently have a Pioneer DEH-P7000R in my bus. Not real fitment problems.
Just a note though. When you install any radio in the Vanagon. pull the
ashtray out. You will be looking right at the top of the radio. This will
make it much easier to get the wiring out of the way when you push the
radio into the dash.
