Sorry For the possible repeat in question.
I'm currently wanting to install a RNSE unit in my vehicle. I have a 2009 facelift A3 sportback, black edition. The car has Bluetooth, steering wheel controls, voice control and aux that I'd like to all work.
Can anyone in the area assist or offer and help on this.
my car also has the shark fin aerial, will I still need a GPS antenna or not?
Thank you in advance for any help.
