Unless I'm able to get my RCD-510 to play nice with my iPod/MDI connection, I think I'm probably going to have to replace the head unit in the car with an aftermarket product. Can anyone offer any suggestions for a good replacement? I like the Pioneer touchscreen units, they have a good reputation and multiple installers have recommended them to me over Kenwood or even Alpine. I'm content with using my iPhone for NAV, so thats not a necessary feature for me. Low key, good quality, and integrates well with iPod, bluetooth and the steering wheel controls. Thanks to all with suggestions.
