Some months back I purchased a Belkin Tunebase FM & AUX Handsfree unit so I could play music from my iPod.
I didn't have a chance to try it out in NZ as I was going on holiday to the UK, so I took it with me and tried it out in my rental car.
It worked perfectly; good reproduction and no interference.
On returning to Auckland I set it up in my Rav4 which is a direct import from Japan and has an FM Expander fitted to the radio.
I've found that I cannot find a frequency that does not suffer from sporadic interference when I use the Belkin.
Consulted the guy who fitted the expander to check if the problem might lie with the car radio or the FM extender.
His opinion was that it is probably due to the proliferation of FM stations in NZ.
I would be grateful for any help or info.
Thanks in advance.
