Early Sat Nav help!

[newscot]

Hi All - Newbie here looking for some guidance please - I've bought an A4 2.5 Quattro Avant Sport and it has satnav installed but I can't tell what type it is! It seems to be the older type which displays on the instrument cluster and has the controls beside the handbrake and the CD reader in the boot. Can anyone tell me what type of satnav it is? I need to find the map disc too, but want to ensure I buy the right one, and I was hoping it might be a generic one like Blaupunkt or similar to make sourcing the disc easier (and cheaper!).
Thanks in advance!

Could be the BNS, think it uses blaupunkt discs

Thanks Kite! As usual, the correct forum draws great advice from those in the know. Much appreciated, just got to get the disc now and hope the system works!
