i'm lookintg at getting a new head unit. the alpine one i have has too many green lights on it (they're surface mount LEDs and allot fo them so soldering new stuff it looks really hard).

here's what i'm looking at getting

i found a place in the uk that said they'd ship it to me if i wanted but they were a little curious to know if it'd work in a us car.

so here are my questions
1) i assumed the differences in cars were based on the manufacturer (toyota) and never regional, and that the wiring harness would hook any aftermarket car stereo up to vehicles of that manufacturer. is this a correct assumption?

2) will i need any other euipment to install it in my car, if i already have an aftermarket head-unit in there? should i get another toyota wire harness?

thanks in advance

It'll work perfectly, radio is only thing that might not work.

cool, thanks a bunch man.
the unit's radio seems to at least support the same fm frequency range so i guess it'll be ok.

Mine is from japan and it works perfectly fine. except for the part that the frequency for the radio is too low.
