Ironically my old Toyota is one of the hardest to really get at sensor and dealer-software changes.
In personal experience, VW manuals are atrocious to figure out while Toyota, at least around 2000 put out wonderful service manuals even if the ECU's are locked down.
It seems like one effect of this is that the temperature display can not be localized. Most everything else on a US market Toyota can be converted to metric but it looks like the AC and internal dash display for temperature can't be changed by the dealer, by knowledgeable users or by repair shops.
