From researching around here, it seems that most everyone runs Kenwood or Sony HU. I have played with car audio a little and liked Pioneer. (Maybe because that's what I've become used to?) Any particular reason not many are running them? I am working on creating a list of parts for my 2009 Electra Glide Standard.

 

I ran a Pioneer headunit for Daytona, many other competitors had Alpines. The Pioneer sounds great....the screen sucks in the daylight. That's likely the primary reason. Also the Sony 70BT and some Kenwoods are "marine" rated.

 

Gotcha...I see the 70BT black/white display now. Was focused on more technical specs/features and overlooked the display in sunlight problem. Thanks!
