Re: Which head units require no wiring harness?
Here is a picture of my installed Blaupunkt London MP48. You'll notice I attached the supplied remote control to the front of the ash tray with some double sided sticky tape. It makes it easier to switch presets or modes. This unit plays mp3 discs too, so you can put about 10 regular sized cds on one mp3 cd. And there's a MIX function that will randomly play through all the tracks. I'm very pleased.
