Want to go to US to buy some Yaris parts, possible ?

[nedjet]

Hello,

It's my first topic here but I've been here quite some times.
I'm in Thailand. Is it possible to go to US, walking in the Toyota show room
to order/buy brand new Yaris parts ?

I want to buy the speedometer which has the cruise control signal,
security, ipod, and door lock switches located at the center console
(in Thailand, there is only AUX)

In Thailand, you can buy any parts in the showroom. Anyway you have to
order and wait for your parts depending on the stock availability.

Is the US the same ? Normally for how long to get the parts after ordering ?
Could I do it in any states of America ?

Thank you so much

PS My car has a very plain look outside, but I need to fully assemble all the stuffs inside.
