While driving to work a day or two ago my radio just suddenly turned off. It will now not turn back on. (at start or when I hold the power button).

It is a Kenwood double din unit.

Any knowledge you could pass my way would be greatly appreciated.

That being said you should check your wiring, most likely something came undone like your Remote wire for instance or your main harness in the back

 

Take it out and check the wires. Possibly came undone like Waizz mentioned

 

remote wire sounds like...

 

make sure your ground is good, plus some aftermarket headunits have a fuse on the back. check that as well
