hey all, I just got an 05 w/nav. When does the mpg reset and can I do it manually? Can I track trip mpg and overall mph?

 

The MPG resets every time you gas it up. If that trip is over about 300 miles then no, because the NAV resets rgw mpg data every time you get gas. You do have multiple odometers though and can use one for a trip's milage. You would need to keep your gas receipts and do the math manually.

 

As posted, each fill-up resets the mpg. I think it is triggered off of the gas door. The only way to track trip mpg is, as suggested, using one of the trip odometers.

 

:sigh... well that kind of sucks, I just gave back an H2 at the end of my lease and recently bought my wife a MB SLK350, I love that feature on both of those. Wish the 330 had it but that's cool. I miss my H2, but I really like the 330, and love the fact I get almost 2X the gas mileage and half the monthly payment. haha

 

I have to admit I am with you - Lexus basically lets you do nothing, at least my GX you could reset when you wanted and it had another display so you could leave milage, distance to empty or outside temp up and have the nav screen on - the RX you have to constantly muck around changing screens to get any info.

It gets good reviews on usability because it barely does anything - I would take BMW's idrive any day over the Lexus Nav, it's faster to use once you get used to it, has a split screen so you can see 2 things at once and has a bar across the bottom with time, temp, date, radio station, radio text and cell phone info, then still has all the driver info stuff in the gauge cluster so you can have the time, temp and fuel economy setting of your choice.

While I am on the rant, it would be nice when you are low on fuel if it actually tried to tell you - the stupid light I can't see from the drivers seat, it gives me only 25 miles to find a gas station and doesn't switch automatically to the distance to empty screen when I get low - it's like Microsoft designed it, except they designed SYNC and it is actually better!
