does anybody know how good they are and how easy they are to fit

i've got one.

digital radio is good and bad ... loads of blackspots ... compression isn't great (see sunday times today) ... but loads of choice on stations and most are better than the local radio junk.

big plus of '53 is the MMC card that allows direct record fro the radio.

my big downside so far has been the loss of 2 ariels off the back window.
