I have been looking for a single din non-flip-up nav unit, like a Parrot Asteroid Classic which would have been great but for all the negative reviews I have read (constant crashing, rebooting, failures, even clumsy track navigation, etc.) to put into a Jeep Liberty with its uncommon oval dash opening. Is there anything, unlike the Parrot, that will actually work? I don't want to butcher the dash to get a double din in, and I HATE flip-ups. I would have loved the Parrot but I refuse to buy junk that fails to perform. Surely there must be something out there?
