I was quoted $180 from my dealer (in Ontario), although the service rep that quoted me this said this is what he thinks it costs and it wasn't an official quote.
He also didn't know what the update does as far as what i get more in 2.1 from 1.3, overall, he believed it adds 911 functionality and he did not think the update was worth the money.
The cost of this is update is outrageous at any price, I understand they made it dealer only upgrade as it might brick the system, but give me a break, it takes less than 10 minutes to do the update.
