IS350 S - 2005 - questions (Firmware/Nav)
Hi all, proud owner of a IS350 S - the Nav system is stuck in Japanese. I'm based in New Zealand but if I use a North America Nav DVD (I think I need Gen 4?) then will that change the language to English at least? I'm thinking it could be an intermediate step before I get my hands on a New Zealand DVD. Also, will the DVD update the firmware automatically? Or is there another method for firmware updates.
Thanks!
Harold
