Bought a head unit out of the states - checked the frequency range before I purchased but I didn't realise they step in odd numbers (i.e. 89.9, 90.1, 90.3 etc. vs NZ 90.0, 90.2, 90.4 etc.).
I've heard rumors you can change Sony headunits by hiting a combo of keys on the faceplate - has anyone had experience with this?
The other alternaitve will be a 0.1mhz band shifter.
It's a Sony MEX-BT3900U
