Hi all I've just put the Nav plus in my 07 Audi a4.all is well I've swapped the 2 pins over to support my Bose. Basically I've read reception won't be as good on the radio which I've noticed. Is there anyway of improving this? Plus where does the gps antenna plug in as if you were looking at back of unit??? And lastly it's all working but making some crackly noise through speakers on start up. Is this because I havnt run vagcom yet?? Sorry for so many questions.also does it matter what maps disk I run and should I have it coded to my car before or after I insert disk. Thanks in advance
