Installed a head unit in the R33 today, however i don't get any radio stations, am or FM, i brought the FM frequency convertor..
If you bought a new Australian head unit - you won't need a frequency converter..
you need a nissan double diversity adapter made by Aeropro AP358a (part no.) from autobarn which takes the 2 prong aerial from the nissan and has a single australian prong..
from what your saying - you put in a new head unit with a freq. converter which isn't needed.. the aerial is a plain old aerial - the HU controls the radio frequencies it receives..
