While I'm having a rant about my pet hates (see my Blue&Me thread), I thought I would also put the world to rights about compatibility issues concerning iPods and Blue&Me.
Blue&Me has a lovely feature which allows you to play MP3 tracks through the USB port in the glove compartment. A normal memory stick will do the trick, just copy your MP3s onto the stick, pop it in and away you go.
An iPod will also work, BUT, it will only work if:
1, It is formatted to PC mode, not Macintosh.
2, It is in "disk only" mode.
3, The tracks on it are in MP3 format, not MP4, AAC, or any other weird and wonderful format.
4, The tracks cannot be downloaded from iTunes, as they are copy protected and do not work on the Microsoft based system.
All in all, whilst an iPod is a lovely toy to have, if you just want it for the car, save your money and buy a £6 USB stick from Tesco, it will do the same job.
