In dash radio replacement?

[grundon7]

existing in dash radio is a Magnadyne M9900 have voltage to unit but no output? Tried extra ground still no luck! Anyone have similar problems or suggestions on replacement?

Actually theres a few things to check.
1) if there is a fuse built into the stereo, usually around where the pigtail plugs into it in the back

2) Typical radio installation will have a hot lead and an ignition lead, both need 12v+ present to turn on

Is the unit turning on ie. is the faceplate lighting up just no speakers? Try checking speaker leads for disconnection. Just a couple of the simpler usual issues i've run across in several different vehicles and stereos.

I suggest you replace the Magnadyne they are many far better CD/DVD/Radio/etc. combinations out there. Replaced mine last year with a DVD changer w/HDMI interface to the TV and love it.
