Here is just a quick review for the Alpine W407.
It works great with the iPod as expected. I previously had the single din Alpine iDA-X001 in my Wrangler and the Alpine X001 loads up the artist name/album and album cover noticeably quicker than the W407. One annoying thing in the X001 was searching for an artist. When you have 60GB worth of music I am sure you know how annoying that is. It doesn't get much better in the W407. You can't search using the keyboard to type an artist name for some reason. You need to scroll down to the artist u want. You can scroll down by letter as in if you are looking for Smashing Pumpkins you can press page down when u r at A and it will take u to B and u keep pressing till u get to S. A painfully long process which I do not recommend while driving. Once you get to S you then have to scroll down regularly till u get to Smashing Pumpkins. Takes forever and not practical at all
Thats the only negative though. The system has a lot of features and options. On the X001 you really didn't have much just bass treble and a bunch of preset equalizer settings for example. on the W407 it gets a lot more detailed, you have high pass filters you can turn on and off, you can see how wide you want to lows or highs, and a bunch of other stuff which I am still figuring out how to use and setup.
The multi display screen is cool, wish I could add more widgets though, weather would be great (could use my phones 3G connection to stream), an RSS reader would have been perfect as well.
Bluetooth feature is cool. I've connected it to my iphone and making calls and receiving calls is easy. I wish it would connect to my iPhones favorite list though because at the moment it doesn't, just dialed, recieved and phonebook etc..
When i select the bluetooth source on the W407 all the sounds my iphone makes gets sent to my stereo which is cool. Playing canabalt or NIN Tap tap revenge is a lot more cooler when your car system is blasting the music. I can now stream music from the web over 3G and onto my car stereo using the app WunderRadio. So for example I am living in Kuwait but I am listening to radio station from Lebanon (my home country) which is great specially since the English music stations suck in Kuwait.
What else is there to talk about. I think I am definitely going to be upgrading my speakers and installing an AMP soon. Probably going with the 6.5" component Type-R Alpines.
