Ok I just got the Jenson VM9423 for my 2000 Nissan Maxima. Bolted right up and the install was very easy. Had the stock radio out and the new one in, in about 2 hours total. Its a very nice radio but has a few issues. Radio reception is horrible. Doesn't pick up stations well. When I do go into town the HD is awesome! I have a flash drive and a sony MP3 player and neither one works right with the usb. The USB is too slow. It connects and disconnects the sony not allowing it to play and the flash drive takes for ever to listen to a song or change a song (it normally freezes the system) The IPOD works well and is fast. It doesn't show the album cover or anything. It does navigate well with the Ipod though. CDs are clear and they don't skip when hitting big bumps and the DVD is super clear but cant seem to get the sub titles to go away no matter what I do. The sound is very clean and the 7 band EQ is nice to get it sounding the way you want.

Over all the unit is nice but has a few issues. Wish the radio reception was better and I could use my sony as I like it better than my wifes Ipod. Oh well for the money I cant really complain. I am planing on getting the navigation system for it. I will let you know how it goes whan I get it.

This unit is a very good product and I have had no problems with it at all! For the price this thing is the bang for your buck. The only thing I don't like about it is when you're using the ipod you have to push the pause button on the unit before you turn the car off. If you don't then the ipod continues to play and uses all of its battery life and then you have to go through and find where you left off. Other than that everything is great! Even the video from youtube through an iphone looks great!
