Its crazy-having talked to two local dealers-their prices vary from $220-$335 for the software update. They also advised against doing it unless there is a problem with the car. They gave me a lengthy disclaimer as to the 'side effects' from updating the software which could result in a number of errors.
Wondering what my options are....feel free to advise peeps.
