Hello!
I have a problem with my dynavin d99+(installed in bmw e90 with business mp3 system) radio reception - it's not stable.
I've followed installation manual from
http://caraudiocraze.com and also re-checked everything.
I've searched the web and found many threads about it but no solution.
Is there a chance that powered antenna adapter will help?
In other manual I read that "amp con" cable from dynavin must be isolated, is it right?
