I bought and fitted this today to my 1998 BMW Z3 to replace an ageing Sony unit and I'm extremely pleased with the sound quality, the build quality and the ease of use.
Simple to fit after purchasing an ISO wiring harness for just less than £4-00 to connect up, the existing aerial plug fitted correctly.
Normal CD's and mp3 are playable and the sound quality is great.
Radio stations are simple to save manually or auto save and along with CD tracks are easy to select by pressing the menu button, rotating the large easy to turn silver knob to select the required track or station then a press to confirm, or simply by using the forward and back button to skip one track/station per push.
So much easier to use than tiny and illegible buttons as fitted to many similar units!
The removable front panel (with option to make none removable) is very stylish and uncluttered and looks good in my car, it's red illumination is a very good match for BMW red glow dials.
The front Aux socket works perfectly with my Sansa Clip mp3 player, if you aren't going to use it (or AM radio) you can set the unit not to show Aux and/or AM radio in the source menu to save scrolling past them when swapping between CD and FM radio .
I found the illumination on default to be a bit bright for my taste but just perfect when dimmed using one of the many useful menu items.
If properly installed and set up correctly using the supplied and simple to understand user manual it's a joy to use.
You can download the user manual from the JVC website before you purchase to check out all the options.
I think you would have to pay an awful lot more to improve on this head unit.
