I've been checking stuff out today and found some interesting results. First, I should explain that our RV has 3 audio Systems. First it has a Jensen Radio/CD player in the dash with weather band and Sirius. That one is OK while travelling. There is also a cheap outside unit with 2 speakers (Not Jensen) that looks like an aftermarket car radio that has a slot for CDs.
That brings me to my problem child. It is mounted in the overhead and tied to the Jensen TV in the middle of the overhead. We have no upper bunk there. This unit is installed behind a cabinet door along with the connections to the 3 different cables, OA roof, satellite dish or cable TV. This is the unit that doesn't work very well. It measures 10" X 7" so that is larger than a double DIN so if I go with something smaller I would need to make up some kind of face plate to cover the hole. I am pretty handy so I think I could do that if I had to. The existing unit has switches for 3 sets of speakers but only one pair is currently hooked up.
Now I don't mind spending around $250 if it gets me everything I have and works. I suspect the original owner paid a lot more for this piece of junk from Winnebago. The Furrion units are interesting but they would require me to make that face plate. The Pioneer on Amazon actually looks like I'll have to cut the hole a little bigger which would work as well. Then I realized that none of these play BluRay which seems to be the next thing to render all my DVDs out of date. I went to Crutchfield but they didn't seem to have anything that matched my search criteria. I even looked at Best Buy but they were pretty car centric. Any other ideas on where to look?
