Speedo to MPH and bits

Forum: 

Hi,

I'm new to the forum. We have changed our vehicle and purchased a Japanese imported Atrai 7.
The radio is one one those double din fitted jobs in Mhz & Khz. All we can tune in to is BBC radio 2!
How do I tune ito other stations?
The speedo is in KPH I want to change it.
Will a UK Hijet 2001 speedo be a straight swap?
This also goes for all the lights. A headlamp bulb blew and it's not a standard halogen H4.
Will UK spec 2001 Hijet lamps fit?
Has anyone completed successfully a rear disc brake conversion?
What parts were used?
Cheers
