For fitting an aftermarket HU to a '99 B5 A4

I believe there are 3 different systems fitting the car that can usually be worked out from the connector on the back of the HU....however, the left side of it will sim[ply not unclip. Am prepared to get it out forceably although only when i have all the bits to put new one in.

So....anyway of telling which system it is? I know its not bose, but unsure after that

Facelift dasah or pre-facelift?

You got the sub in the back?

Er, not sure the differences between dashs?!

Also, where is sub located? Is there a speaker grill or not?

99 should be facelift, and you will have an amp driving the rear speakers. You would know if you had Bose as it would be on the speaker covers.
