Look into aftermarket GPS solutions that tie into the MFD, or as a second best, standalone displays. (coastaletech is a good place to start). If you find something that satisfies you, the available option packages will be less restricting. Also, keep in mind that GPS is hot these days, and more solutions are likely to come to market.

I side with Jason in giving a really big thumbs up to SmartEntry/Start. I also personally made VSC and multiple airbags a mandatory buy. The rest of the options on my full featured Prius don't really knock my socks off. People wed to their bluetooth phones may feel differently :-)
