I installed a NAV head-unit, and any suggestions to deal with the gaps on the trim?
Put in a Kenwood DNX571HD, it comes with a useless faceplate. I'm guessing the Pioneer/Bespoke is not DIN standard size?

(I am going to start a thread with all the wiring and stuff, as that was most of the work and a bear)

 

Did you use a radio fit kit? for a 08-up scion xB ?

 

Go pick up a Metra Electronics Scion xB dash kit. It comes with little side panels to fill the gap on each side. It looks like you will also need to use the radio trim bezel as well, there is too much gap on the top and bottom.

 

Thanks, I finally found it

I put together a 2013 xB Radio wiring diagram, after trying to buy it. Should I post here or a new thread with pics?
