hi, i have an Australian W210 E430 1998 model. seeing as my head unit is a little worse for wear i was hoping to replace it with a new unit. the prices in Australia are ridiculous. the prices in the USA are much much better, and my sister, who is coming over in a few weeks from San Diego can bring it over with her.

i just want to know if the parts are completely interchangeable otherwise its off to the Aussie wreckers to get ripped off again.

cheers guys... this is my first post so go easy on me.
