I am looking to get a new head unit mainly for bluetooth use. I currently have a old pioneer car unit right now. Last year I purchased the Clarion M502 unit for its bluetooth and marine quality but had a defective unit and did not like the interface or all the cables hanging off the back. so returned it. The problem is there really isnt to many units with bluetooth. I came across the Dual AMB600W
http://www.dualav.com/marineaudio/amb600w.php which is marine grade and has bluetooth which I tested out at West Marine and walked around the store to test the distance. My other option would to go with something like the Alpine UTE-42BT
http://www.alpine-usa.com/product/view/ute-42bt/ unit which is bluetooth a bit cheaper but not marine grade. The unit will be going to a rockford M600-4D amp to power 2 in boat speakers and 2 tower speakers.
The reason I question getting marine is due to the radio installs into the driver side dash, leaving the back of the unit exposed to moisture under the dash, but I have also had the pioneer installed for a couple years without any issues, except some corrosion on the mounting sleeve and on the back of the unit.
My question is should I go with the Dual brand marine grade or go with a more reputable brand like Alpine, but not marine grade.
(I dont care about CD's just bluetooth and aux in port)
