I agree with cbibbs on the curtosy wipe thing 90% of the time, although I find myself imitating it manually on the HCH since the windshield is so raked on that car. However, sometimes it does seem to help.

One thing I didn't mention which may or may not be a selling point for you. Between folks like DesertDog and GPSman1, and Linear Logic's support, you can know almost every possible detail about what is going on under your hood with a Scan Gauge. Go to Linear Logic's site and look at what is available for the Prius (SoC), the HCH (nothing), and the FEH (everything I've ever wanted to know about my car). It is an analytical geek's dream come true!

That being said, I would still pop for the Nav system since the graphics are sometimes easier to decipher than the numbers and raw data from the SG.

Commuter car, grocery getter, and summer road tripper--average 10k miles per year.


Winter road trips and ski trips, bad weather commuter and my wife's "daily" driver--expected average 4k miles per year.
