Gapless music playback

Evening chaps and chapesses'

Something that constantly irritates me when im listening to music in the car is the gap between songs.

When i'm listening to a mixed album that has each track separated, there is a gap of about 1.5 seconds between one finishing and the next one starting.

Car is a MY15 S3 SB with Tech pack + Connect, i play music through a USB plugged into the AMI cable.

Does anyone know of a way to get it to play music without a gap between tracks?

Ive changed the properties of the tracks on itunes so it doesn't have a delay, yet it still has the delay when it's playing through the car.

I've had a look at the settings on the car and cant find anything that relates to it.

EDIT: The AMI cable i'm using was brand new when I picked up the car in April

Any info would be greatly appreciated.

Thanks in advance.

I've just checked what it does with a mixed CD in the CD drive and it plays it without a gap!
