Default Garmin 4208 - Radar and XM Weather Problems

So I have the 4208 with 48NM HD Radar. The unit is brand new. We are playing with the boat today and trying to re-trace the wiring to figure out why it is acting the way that it is. I will be calling Garmin tech support tomorrow. The radar receives a "lost signal" or "radar needs service" message after running for 10 minutes or so. The unit seems to "lock up" when this message is received. My XM subscription consistently reads "no subscription" even though I call XM and they show it fine on their end. XM will send the unit a signal and it sees it fine. But, when I power done and come back later to play in the boat again, it shows "no subscription", even after waiting several minutes for it to load. It won't show the subscription again until I call XM and have them send another signal.

1) Reading up on problems with the 4208, we are double checking voltage issues, wiring, power connectors, software updates, etc..

2) Anything else I may be missing?

3) I hope Garmin will warranty my equipment. The units are less than (1) year old. If for some reason they do not, what is the best system to have on board? I keep thinking I'll go back to the Furuno Navnet, but I want to know who makes the best with the least problems.

Thanks for your time.

Just have your receipt. That's what Garmin uses. I talked them into sending a PCB to the local service company and they swapped it so i didn't have to ship that big unit back.

I believe we got it figured out - - seemed to be a voltage sensitivity issue. When you run your radar & all your electronics for an hour in your driveway without a alternator running or shore power it tends to drag your batteries down
