hi, i recently purchased my 1st car, an old merc 190e  on impulse cause
it was going cheap at an auction and it came with a blaupunkt cambridge
sqm 39. now to my tone deaf ear it does sound ok and the fact its an old
tape player makes it less likely someone will smash my window and try to
steal it hopefully.

the thing is i have a pretty huge music collection (about 4000 songs) on
my iaudio M3 mp3 player and would like to listen to them in the car and
was thinking of getting a tape/radio adaptor and i have 40 gigs worth of
mp3s in my car for under £10.

now the only problem i have is that tapes used to hiss and it was
annoying, i read that the radio transmitters may do the same, anyone know
which is better.

failing that would it be worthwhile  upgrading to one of the £70 stereos
you see on ebay which have a usb socket which allows you to connect an mp3
player to it. im not sure if these only work with the usb stick mp3
players but my iaudio isnt locked down by any or the drm crap a lot of
disk based player are so may be ok.
