"Yeah its easy. tape or cd players- its the same"
Maybe. Leslie, you said you have a Ford. Is the CD player separate from the radio, or is it one large unit? What year is it? Newer Ford stereos have a mess of wires.
If it is one large, tall units, then it is probably a double DIN stereo system. Need a special tool to remove it. Also if you have a PATS system, then there is a security system, so there are a whole bunch of wires back there.
If it is a separate CD player, then the wiring goes through the radio, which is the amplifier. Again a bunch of wires to deal with.
Whichever it might be, it is likely you will need a wiring diagram to figure it out. And since Ford uses special plugs, you will either need to cut and splice a bunch of wires, or purchase special adapters. You might want to go the the Crutchfield Website to do a little research.
I drive a lot in remote places where there is little or no radio reception, so radios are often useless. CD and tapes are a pain. MP3s, especially iPods are wonderful.
A few years ago I upgraded the radio in my Ford, instead of buying a new vehicle :)
Probably more than you would want, but it has navigation, bluetooth, satellite radio, ability to hook up a rear camera, ability to hook up video, and iPod. I bought a lifetime subscription to Sirius radio. For me the system works well for those long trips across vast deserts to Arizona, Nevada, Utah, New Mexico, or up Highway 395 in California. I find I usually listen to the iPod most of the time. Also, I like the ease of selecting music. The touch screen works similarly to my iPod.
