Hi, i need to change the radio Ariel on my golf but because i have sat nav it has got the gps antenna at the base of the Ariel,

my question is can the Ariel be purchased separate from the antenna or do you have to buy the whole sat nav Ariel,

if so does any body know part numbers for these?

Any help would be appreciated, I'm a new member and am finding this forum very useful.

Just realised posted in wrong section, its a mk4 not mk5 golf.
