Alpine MM screen differences

[Chase]

Does anyone know the difference between the CVA-1003R and the CVA-1004R Alpine MM head units?

I've keep seeing both about, but can't see any differences between them?

Cheers

MATT !! Got any idea about this dude?

Errr, ones got a rotary control and retails for £200 less! (Both the 1004 BTW).

Give me a call at work on Tuesday and I'll go through the book to check for differences.
