This is great unit. The CD player is fine. The Tuner is fine. The Aux input works well. I prefer to use the USB slot which is very handy for quickly grabbing podcasts or whatever before you hit the road.
The bluetooth phone facility works reasonably well unless you are tanking it up the M6 in a mk3 Golf in which case there is a background noise issue.
The previous reviewer rather misses the point. Berating the unit for not being compatible with your iPod when it doesn't claim to be seems a little silly. (The iSheep can be a little fascistic, can't they?) I was disappointed with the lack of onboard toaster, but as Sony make no claim that this facility is present then I suppose I'll suppress my complaint.
Anyway, this a great little headunit which does pretty much everything you might want it to. It also comes with a remote control which I'm struggling to get the full use out of.
