I installed this on
Mazda 3

Review
The biggest pro for me is the sound. My stock speakers sounded good with the factory head unit, however they blast like brand new high end speakers with the Pioneer. A close second is the feature set; the iPod integration is the best that I saw in any unit, and it sure beats the auxillary input mod kit that I was running beforehand. The sound from the iPod is great. Also keep in mind that it has a USB input, not an iPod input. Plug in an external hard drive or thumb drive and you're good to go, too. The addition of the Bluetooth connectivity was a major selling point, and it delivers a great convenience that I would really miss now that I'm used to it. I can leave my phone out of reach and I can still answer it if it rings. However, the biggest con is the user interface- it does take a bit to learn the ins and outs, but once you do, very few times is it a bother. The pros VASTLY outweigh the cons, and the price is far below what I would expect for a unit with this feature set. iPod, Bluetooth, CD, HD & Satellite Radio ready - there really aren't any features left for you to want! I purchased it with the wiring harness and the dash kit for my 2005 Mazda3 and it looks quite nice.

What I like
The blasting sound quality, the amazing connectivity through satellite and bluetooth, and also its great features!

What I do not like
Quite difficult to get hands on this unit!
