There are a number of companies that make aftermarket interfaces for factory radios with a couple of options mentioned above. We went with the USA Spec BT45-TOY.

You need to consider the full situation of those making such statements. If properly cared for it won't have problems starting after a few days. There's something more to those situations that you're referencing. As always: always consider the source.

As with any vehicle, depends on a number of variables -- especially how one drives it. There's no way we can tell from your posts what you can reasonably expect as we know nothing about your typical driving style and conditions. Your best bet is to compare what you get real world versus sticker on your vehicles and extrapolate from that.

You need to decide based on your own needs/wants/priorities/etc and not on just polling random people (same as any other topic). I'd get the hybrid for the added power but my priorities don't seem to be in line with your own.

I think I ran across a solution that involved creating a group to sync. Didn't apply to me (iPhone can't transfer to the 08) so I'm not 100% certain that I'm recalling correctly.

There are aftermarket bluetooth kits. I have no idea which ones are compatible with the RX400h but most vehicle-specific products have a section on their site with application guides. You could also connect an aftermarket aux in and connect a bluetooth audio gateway. ...and there's always replacing the head unit itself.

Can't speak directly to the 2006 RX 400h but the general rule of thumb is that you can use lower octane unless you get knocking. Higher octane can help to eliminate knock. See also: http://www.ftc.gov/bcp/edu/pubs/consumer/autos/aut12.shtm
