I just bought a Sony CDX-GT300 from Halfords for £149. I know I could have got it cheaper but I wanted to replace the Ford unit in my Focus before the local lowlife got their paws on it. There seems to be a part in the Ford units that can be used to get free SKY TV so they are a natural target to be ripped apart and sold on the black market. Anyway, it was fairly easy to fit. I heard horror stories of Sony car players requiring Sony speaker but not the case here. Sound quality is pretty good for the price I must say through the CD and the tuner is pretty cool too. The front AUX is well useful for docking my HD5 but to be honest, ATRAC CDs can contain upto 22 albums on ATRAC3 Plus so I doubt there'd be much call to do that, especially as it results a a wire dangling all over the place on the dashboard! The entire front panel comes off which makes the head unit pretty useless to nick but the one thing I hate about it is it's so feckin' fiddly to remove and replace! But overall it's a very good unit for its price.
