I believe it was a video - maybe one of the Japanese ones with subtitles - and you could hear the distinction between the Toyota chimes and the Subaru ones, at least in the cabin. Horn may be different.AFAIK, Toyota uses the same security setup as Subaru and the vehicles sound the same when the fob unlocks if you have audible signals enabled.
Right. And I did not say alarm set alerts.The alarm set arm alerts are not usually the horn these days, of course. So yea, the actual horn may sound different.
