Hi, I have searched the forum and could not come up with a definitive answer on this. What is the best tire to put on the 400h? Is it Toyo, Hankook or Michelin? Thanks

Thanks, I appreciate the information.

Thanks, no excuse for the typos. I could say the cat was helping me.

Sorry but here is another nube question. Do I really need to use premium gas in my 2006 RX440h? I asked my service adviser and got a long story that meant yes use premium. I need to know what owners think. Thanks

Another newbie question please. The navigation screen on our new (to us) RX400h blacks out for a few seconds every once and a while as we are on a route. Does this happen to anyone else? Is this a normal function? I looked around the forums and did not find anything on it. I am used to using a Garmin.

I had the Version 5 that came with my 06 and updated to the version 7. I lost the cool feature where I could by pass the system so my passenger could use the nav while I was driving. I didnt gain a thing otherwise and was upset that the things I wanted to see added to the nav where not there. I have called all over trying to get a couple fetures added. I am no bible thumper but when I am away for the weekend it would be nice to be able to serch for churches. seems everything else is there from community center to marina. My auto repair shop has been in business since 1956 and I am not even listed. Not sure who ya talk to in order to get things updated. I have talked with Lexus Corporate but they were not sure where to really send me. Do you have the steps needed to allow a passenger to control the nav system while someone else is driving? Yes, I do. That was one of the first things that I found on the web. My wife was very happy about that. It is a shame you have to redo it when you turn off car. Thanks ;)

Thanks for the replies. The information is very helpful. I don't think that we will be upgrading anytime soon. I don't want to loose the ability to override the Nav plus the price that Lexus is asking for the disk.

We just purchase a RX400h and are very happy with it. Can anyone tell me the difference between the navigation v5 (installed in purchased 400h) and the new v8? Do i need to upgrade?
