hit the road......Just so you know, the Magnadynes had an issue with the power lead where the two connectors come together at the back of the radio. The leads make a poor connection and cause the radio to lose power and the CD skip from loss of power.
I tossed mine and put in a Pioneer Avic (many levels of the Avic) AM/FM/XM/CD/DVD/GPS. It has a large screen and plays the voice directions through the stereo speakers.
The Magnadyne is a 1.5 DIN. Radio openings come in 1.0, 1.5 and 2.0 DIN. The size refers to the height of the opening. The width is standard. I enlarged my Monaco to a 2.0 DIN to install the Pioneer. It's just a matter of cuttig the dash panel opening a little larger and then slide in a new frame which will come with the new radio.
