Anyone have any experience with Jensen?

I'm asking because the RV came with Jensen VR187 & the display quit working. They won't do anything about it under waranty (said it should be covered under Coachman warranty). It appears that this unit was made special for Coachman & there are no direct replacements. According to Crutchfield, it's not even a standard mount (1.8 DIN). The video connectors are custom as well.

The good news is that a remanufactured unit will ONLY cost me $350.
