Summary: I recently bought this deck as an upgrade from my budget deck(Dual) expected this thing to run like a champ. At first I loved the design of the deck and the features it had. Than realized those so called features cost extra to use with a separate console "imprint". Bummed there but the deck still has built in crossovers for your speakers and an internal amp which I have to admit is pretty GREAT compared to my dual deck.
Summary: I've been installing car audio stereo equipment for years now. I've attended and competed in many car audio competitions. Alpine head units are very popular in the competiton world. In otherwords, you cannot go worng with a alpine headunit.
Summary: First and last alpine receiver. This unit stinks. 1. Same button to turn off unit as to switch between inputs i.e. cd, tuner, etc. If you don't hold the button long enough, instead of turning off, you just switch inputs 2. When receiver is off, there is no clock, so unit must be on at all times 3. Ipod navigation is slow as snail and tedious to use 4. Very little audio adjustment features for the money. 5.
Summary: I really don't have much to say. I've had an Alpine head unit in the three cars I've had in my life. I don't think I'll ever stray from them. This unit definitely does exactly what I want it to do. I wish it had a Zune hookup because I had to pay $100 to install an auxiliary input for my Zune HD. For some reason, I still think my CDA-9815 that I bought in 2003 for my '00 Honda Civic Si was a lot better.
Summary: I have had the stero for less then a year. I have the same problem as another user. Error 01. Nobody knows how to fix this, except get a new radio. They (Alpine) don't seem as good as they used to (quality that is).
Summary: Fundamentally, the sound quality is great. I like the 4 volt pre-outs because I'm using a separate crossover and two amps. Overall the sound is excellent. But the menus--ugh, not at all intuitive. I have three major gripes: 1)No mid EQ--WTF? Both of my former Blaupunkts had treble, bass, AND mid EQ and for less money. With this thing, you need to buy the extra "imprint" system for lots more $ just to have a mid tweak.
Summary: MP3/Hard Drive issue : I have always been an owner/user of Alpine recievers. Before I purchased this model, I wanted to make sure that the reciever I purchased had a usb input and had the ability to play mps's straight from a hard drive. It plays them just fine; the problem lies with how the unit navigates the file structure you have set up on your hard drive.
