We have a '98 Gold Badge LS400 imported as Celsior from Japan. The Sat Nav and console are still in Japanese, is there a source for English Language Chip-set to convert. Not worried about the actual switches being Japanese, but must ensure that the new chips don't upset the ECU and Security System

On Security - I have failed miserable to get a new key cut and programmed for it. Lexus UK say that they don't have the codes required to programme a new key.

HELP!
