Ok headunit.

I bought this for my truck and have had mixed feeling about it. The touchscreen always works but I have had it freeze and I had to turn it on and off to get it to work again. Also the volume control is very very touchy which I do not like. Everything else works fine. The remote is great and also the iPod connect.

Junk

This unit is junk, volume up doesn't work so i have to use remote. Microphone doesn't pick up anything, have to yell right by unit to almost hear you. Tried to contact Boss too and no success.

Make a Different Selection!

Basically this unit functions as advertised. The probem is that it's difficult to use. The LED display makes all the the functions very tiny almost impossible while you are driving, you have no idea which items you are selecting. Also when you attempt the adjust the volume control your finger brushes across the menu tab and all of sudden you are now adjusting the bass instead of the volume. Very fustrating. When you need to silence it quickly, The mute button is hard to find and not much help. I selected it because of its bluetooth function to answer calls which it does. However the caller can't hear me it has no external microphone. If you look in the owners manual it suggests you resolve this by having your caller turn up the volume of thier phone. Ya right!! I've removed this unit from my service truck and put in my old truck i dont use very often.

Value, features, but defective unit

Pros: Nice feature set (usb, sd card, decent sound, bluetooth capability, remote)
Cons: defective mic, touch sensitive buttons

A great value unit with a nice set of features. Probably not for the audiophile, but works for me. If it worked, that is: the built in microphone for bluetooth hands free calling was defective in the first unit I got. Replacement under way... will update.
I also noticed the touch controls occasionally stop responding - this may be related to weather conditions, and I believe it may be an inherent issue in the technology itself.
I reserve to update the overall rating once I get a replacement.
