Interior Illumination: Here's a
link to a pic of the interior with the illumination kit. I considered it, but there's a cubbyhole on the left side of the dash that you'll lose if you get the light kit.
Gauge Trim Kit: It's not available for models with navigation. See
here for more details.
Run-Flats: No, they don't. They're plain old low-rolling-resistance tires. Traction's not the best.
I would recommend--if you can--cancelling the wheel locks, exhaust finisher, and floor mats. The prices at the Honda dealer are obscene, and even the least mechanical person can install these on their own. You can get the same genuine Honda parts from
H and A Accessories or
College Hills Honda.
If you're more mechanically inclined, you can do the bass kit, and some here have done the auto-dimming mirror. I looked at the instructions on installing the foglamps and decided to get the dealer to do it.
For what it's worth, we got ours at
Bay Ridge Honda in Brooklyn. The salesman (ask for Frank!) scoured 4 states to find one with a Nav system. We picked it up a week later. He really knows his hybrids, as does their service shop. It wouldn't hurt to give them a call and see what they can do for you.
