For my mirage, I searched and searched for the stock 1980 AM/FM Cassette player with Digital Tuner.. Finally found one. Haven't installed it yet.
For the "Real" sound... I have devised a mounting system that hides a Modern CD Player (mine has XM capability that I will add soon) under the dash just to the right of the shift console... It slides down and out to use, and slides up into the dash when not being used.... I haven't built it yet, but it looks good on paper, and all the measurements fit...
For example, from the "use" position, the unit would slide straight down 1 inch, then pivot 20-30 degrees forward, and slide up under the dash...
I'll see if I can find my drawings somewhere, and maybe someone will actually make it and tell me how well it works
Later,
Adam
