I am looking on purchasing a Jap RX8 with Sat NAV. Only problem is the NAV system will be in Japanese. Does any know if it has the option to switch the system over to English in the setup options?

If it does, would a european NAVTECH Map CD work with it?, or does the unit need to be hacked/firmware upgrade.

Currently I am trying to source a company in the UK that does conversions but I am not having much luck.
