Only having my 130BT, I am no expert. However, the Voice Recognition has been fine for me. I do however have to pronounce the names as per their origin.
Weiss, is Vice. It knows its a German name.
Fujii, is Fuji-(super soft i). It knows its a Japanese name.
Its knows that Joann, is not Joan.
The confirmation is annoying and you should be able to turn that off, on principle. Though I did not find it in the manual.
The Address entry is total bunk. But some of that is the Catalog. And yet, its still better than what came with my wife/owner's Sienna XLE Limited.
