Great head unit for the price. All I was really looking for was a decent head unit that could play Mp3 discs; the Bluetooth was a definite plus. Sound is great and streaming Bluetooth audio from my phone is definite sweetness. Only problem is with that...

Mp3 disc playback ; Bluetooth calling ; Bluetooth audio ; Sounds much better than the 9 year old aftermarket head unit I had in my car :-)

As other reviewers have stated, people have trouble understanding me while using the built in Bluetooth on the unit. Seems to be an issue with the microphone, even when speaking loudly in a non-moving car

A great deck for the $$


Installed 2 of these to replace outdated decks in a Lexus LX470 and Mercedes C230. The Lexus required a large face-plate. Recommend installing an additional cubby for glasses, phones, etc. Overall Love it!!!!

Great blue-tooth connectivity. I listen to audiobooks wirelessly from my iPhone. If a call comes in, the iPhone pauses the audiobook, answers the call through the deck and then resumes after the call. What else can you ask for? I can't believe...

Does not show track being played from audio device. 3 cycles of FM before you switch to AM stations. Not enough sensitivity between volume click levels. There is some audio where setting is either too loud or too quiet between clicks
