Dash Heat and Radio Failures?

Driving home late Sunday after another "Rush the Field Purdue Win" on Sat.
I pulled over to connect the antenna on my Sirius Radio. I removed the little square cover on the top of the dash with the black rubber insert above the radio.
It WAS HOT! I mean REALLY REALLY HOT! My radio wires and cables were like limp wet noodles... I did leave the cover off the rest of the way home.
My questions are.
1. Anyone dismantling the dash know where that kind of heat leakage would be coming from?
2. I think this heat could be the cause of all the Radio Failures?
I will be leaving it off for a while. I am thinking about adding a vent or install a computer fan under that tray area pointing up. Next time out I will take some temp readings (not sure when that will be).

On our 2017 Axis 25.2 during cold weather that necessitated using the cab heater, the camera view screen on our Axxera radio would stop working, turned out that the heat ducts where routed in the same area that the camera switcher was located in and this generated an extreme amount of heat under the part of the dash. I insulated the duct work and the problem was solved.

Were you running the (engine) heater? Maybe there is a loose vent allowing heated air to accumulate under the dash.

Yes, I was. I'll poke around in a few days. Just thought others should check due to the fact of so many radio issues including my own I replaced.

Well there is that and the fact that the radios are junk.

Totally agree! ( I was actually happy my Axxera died) Just a heads up for people installing $500.00 plus systems.

Iíve found that the heater duct routing under the dash leaves something to be desired. I adjusted mine ad made sure all were connected. I also purchased some denim insulation from HD and installed it under the dash for heat a noise control.

After the plastic dash. How is that covered flat piece or the slant section with defroster vents fastened for removal? I see no fasteners.

If youíre talking about the fabric covered piece up near the windshield, I didnít remove that on mine. I removed the large plastic cover on top of the dash as well as the computer work station to gain access. If youíre looking to check the ducting connected to the defroster vents then I suspect you could pull those vents off and look in. I know that on our Coach that there are several ducts running underneath and behind the radio. That radio gets hot under normal conditions. If someone had a leak in their ducting under there then that would definitely make it worse.
