Sash_RX400h

Oh, boy, you are reading my mind :) - I had the same question in my mind and was going to post it , but you were first!

I get about the same range - ~2 miles or 15 minutes in bumper to bumper traffic.

It is 2008 RX400h with 31k miles on it.

I don't know if it is logical, but I was hoping for more...

I'm still frustrated with the fact the the navigation goes off when you're moving. It's amazing that you can program a tom-tom when you're driving but can't the Lexus navigational system. I'm toying with buying the module to defeat it. Anybody have experience with it, good or bad?? Thanks!!

I know, it may be too late for, but have a look at this vid - maybe it will help you to defeat this navigation system's behavior:

Will this procedure improve 2008 RX 400h performance? Is there a potential to hurt anything in the vehicle?

Just got used 400h last Monday with 30k miles on it and have noticed that it has Toyota battery under the hood.

Is it a good idea to replace this battery with a different one?

Sorry for too many questions, I've been reading this forum for the past week, but this is my first post.
