Didn’t exactly get a total brush of just yet, but I did get sort of a shoulder shrug:

Track Firmware version 49 does not sound correct for GROM-AND2 unit.
What I recommend is seeing if you can flash firmware version 40 which is the latest for your vehicle type and see if it helps. This is all I can suggest. Other than that, I am stumped.

OK, I’ve downgraded my firmware to 40 even though when I went to
http://gromaudio.com/software-usb2.html the photo at the top of the page says, “Top Part Has No Lip” and my unit clearly has a top lip (see attached photos.)
Is my unit some sort of USB3, USB2P variation so that firmware 49 would be right for something purchased last summer?
Is this my serial number? 03-18-031314? Those numbers match nothing like shown on either page…confused.

I doubt I’ll hear back.
If my theory of this all being heat related is correct, it probably doesn’t matter what my firmware version is. GROM has no real competitors in this arena, so the only options if this thing keeps messing up is to buy another box from them or swap out the head unit. I loathe the new head unit option on several counts, but I don’t relish the thought of spending $150 on something that might only last a little more than a year either.
But now that the weather is cooling off we may be in for some trouble-free listening ahead. Might be able to put off what to do until mid-spring.
