Hi guys! I'm driving '07 Lexus IS250 (5th gen navi.) here in Poland. I've imported it from the USA. I had hard time trying to run European version of navigation maps, but I finally did it. I've used "Toyota - Lexus navigation map Russia 2008-2009 ver.1", you can easily google it if you want. It contains maps of "Finland, Lithuania, Latvia, Estonia, Czech Republic, Slovakia, Poland, Hungary, Romania, the main road of European part of Russia". I guess that if I managed to run this maps in US car, you can run UK and other maps in your cars. I've used standard Verbatim DVD+R disc (not double layer) and Alcohol 120%.
Original DVD that I had in my car was U31D (v.6.1)
