The MP48 also perked my interest with the plug and play feature of the wire harness.

Problem is that when I google and search for the MP48, they are not available (or at least I wasn't able to find one).

Even eBay returns a search of zero (which leads one to believe none on the used market).

So I skip the MP48, as my dream unit is a pop-up LCD screen, bluetooth for hands free calling and music streaming from my Andriod fone, Aux/MP3 and USB front jacks, and lets throw in Garmin GPS. And it's all built into a single headset.

I think Kenwood has a model and features Garmin...!!!

Pig heaven for the techie at heart...
