I know you guys have probably figured it out already, but it took me about half an hour to find the bloody radio fuse in my T4.

Beneath the main row of fuses under the dash (behind the storage pocket) there's a little black box. This slides forward to reveal more fuses (in my case only 2) including the one for the radio.

Only reason i thought i'd post this up is they don't mention how to get to the bottom row of fuses in the manual, and on the side of the road i don't think it would cross anyone's mind to pull apart something that looks like it's not supposed to come off.
