Hello all. I just pulled my 2017 Jayco Greyhawk out of storage gettin ready to hit the road next week. The Jensen radio has not power at all. This head unit has Navigation and also controls my camera...

I don't know if this is related, but I posted about my Greyhawk's Jensen JRV215N problems over on the Jayco Owners forum. My solution might help. Turns out the JRV215N goes really wonky if the coach battery dies.
The way I brought it back to life was: fully charge the coach battery.
Then master power switch off. Then disconnect coach battery completely. Then disconnect chassis (Ford) battery. Wait 30 seconds and reverse things - reconnect chassis batter, reconnect coach battery, master power switch on.
This worked for me. It might not be what's wrong with yours but it's worth a shot.
The Ford fuse that's there for the radio does not connect to the Jensen in our unit. It's #39 (IIRC) and is behind the parking brake. But pulling it had no effect on the radio in my Greyhawk.
If all else fails, you can try ASA Technical support. But they were no help to me. Somewhere in your coach should be the two metal 'prongs' that will allow you to pull the unit out of the dash.
