I'm going to fit an aftermarket H/U to my R32 which has the dual diversity antenna system with antennae in the front and rear windscreens. It has a two prong plug at the back of the factory H/U.
I've done a search but I'm still unsure what is the best way to change it over. It seems to me that the factory system is just adequate but not that good anyway. I guess that could be because the factory antennae are optimised to the slightly lower japanese frequency band or maybe antennae in the glass are more directional than a vertical antenna so reception varies depending on which way the car is headed.
Should I fit another antenna? If so, what type and where? or should I use the existing antennae and just buy an adapter for the plug? Is this good enough? I have my doubts.
What's your radio reception like?
