My GLA has been sitting for ~2 weeks and when I got in it today, the screen for the MMI wasn't working. The radio worked, but no display of any kind. The backup camera didn't work, nothing. It was playing songs from my iPod just like it usually does, and the volume knob worked.
I doubt this is related, but I'll mention it anyway: I'm pretty sure my battery was not fully charged after sitting because my Eco Start/Stop didn't start working until I had driven ~50 miles today.
I researched this a bit and tried resetting the radio with the long-press of the "Eject" button, and that did seem to reset something because after that it wasn't playing the iPod anymore, but it would still play the radio or CDs. Alas, still no screen though.
I checked every fuse that said anything "Command" or "Audio" and they're all good (I really had my hope set on fuse #37).
I am still covered by the MB CPO extended warranty. But, I have an aftermarket Android interface box tucked into the dash (that's how I managed to get a backup camera into my no-frills GLA). So, I assume I'll have to uninstall that whole thing, lest I be told it won't be covered because there's something aftermarket installed (oh, and here's the bill for our super-special, uber-expensive tech to have determined that!)
I feel like if I have to rip apart the dash again to uninstall my RoadTop Android/camera interface, I might as well just do an upgrade to a newer, larger screen. So, like, why bother going to the dealer if it still means a ton of aggravation anyway?
I just wish I knew for sure if it was the actual screen. I don't even know how to test the screen to see if it's the screen itself or something further into the mix.
Any ideas for what else I could try?
