I haven't really been on the boards lately so I will apologize in advance if this has been discussed somewhere already. I got a call from my dealership informing me that an upgrade was now available and I could make an appointment to come in and have it done - 2 to 2 1/2 hrs to get it done. The thing is I've never had any issues so I'm thinking maybe I should skip it. What do you guys think? Is there an advantage to getting it that I'm maybe not thinking of?
