Cruse controll in standard in US, but not available in Europe.
I liked cruise control on my previous cars and miss it a little on my RX8.
Does anyone know if it is possible to install it in a European version of RX8?

 

u probably could but would be a lot of work

 

Should be possible with US parts, but probably pretty expensive.
1) You would have to check if you have a harness there, you'd need the wiring diagrams to check this
2) You'd need a new steering wheel with the controls (maybe order from US)
3) You'd either need a new PCM (EXPENSIVE!) or to have the parameters in your present PCM reset. PCMs have pre-programmed non-changeable data, and some programmable parameters (like wheel and brake size etc.) If there is a parameter for Cruise/No Cruise the dealer would be able to just switch it on. If not then you will probably need another PCM.
I suggest you ask if US dealers have retrofitted to US market cars yet. The guy from Rosenthal Mazda might be able to help you out (there are NO secrets with him!)
Good luck!
