Head units from the US ? gotchas?

[shueardm]

Does anyone know which are the most compatible units bought from amazon for use in Australia?

What about the SONY XAV-70BT it is even the same model number.
Would I presume this would be region 1 only and what about FM tuning.
Any experiences?

Why would you buy from the US?

not sure on the dvd side of things, but AM wont work at all, FM works in 200khz steps instead of 50khz, so you'll miss out on some stations. us fm does 99.5, 99.7, 99.9, etc. aus fm does 99.5, 99.55, 99.6, 99.65, etc.

wraith, units from us are much cheaper than retail on units in aus.
