my sat nav doesnt need the extra aerial Works spot on
Did you get the Tom Tom Go 700 model?
no I have Mio 269, which came with extra aerial, but was not needed in the Zed
The extra aerial is only needed for cars with front windscreen heating strips. Only certain cars have these though. I drove a Mondeo a while back and it has a kind of mesh on the windscreen which is only visible when you get close up. Apparently though this has a negative affect on recieving a GPS signal
