Pioneer radio went dead during drive

[Hammond]

We have a 2017 FR DS30. We are very new to motorhomes. Our pioneer radio was working perfectly, backup camera, etc. and then suddenly died. We've looked for loose connections but the power won't come on to the system at all. We reset per instructions, no luck.

We are trying to find the fuses for the radio, but again no luck with the manuals.

We are under warranty but the dealer is 3 hours away, trying to avoid this trip.

Thanks for any help or suggestions.
