Hi Malc I had a look but it didn't help..Anyhow I bought the car and use Google translate on my phone but it's not ideal. My unit is not like others I've seen. It also has a mini disc and TV. There is also a hard drive in the unit where the sat nav is stored and music but it says I need a lexus tool to update this which seems to be via a WiFi connection. Lexus website doesn't recognise my vin number and of have to pay for it anyhow. Everything works fine.
