I have a 2007 EXT. I just ordered a new 2011 Nav disk. I have read in some places that there is a firmware upgrade for the 2007 models. IS this true and if so where can i get it? Will my 2011 nav disk work without the upgrade. And if a dealer upgrade, will they charge me?

I can't answer your question, but I just got a 2011 disc for my '08. It went through an update when I first put it in the slot. Took about 5-10 minutes and warned me not to shut off the power or change the key position so I am guessing it went through some sort of firmware change. Someone correct me if I'm wrong.

That's correct, it does the firmware upgrade automagically!

Perfect, thank you. That is what i was hoping for.
Same here. Placed my new '11 nav disc in the dvd slot. 10 minutes later, presto, new '11 nav disc is operational. I cannot notice a 'huge' difference, however, I am certain that streets, poi and locations have been added and updated over the previous version(s).

Maliburider, it looks like you've gotten a pretty good amount of accurate answers here but if you would like I could escalate this question to our Technical Assistance team to see what they say about this question. If you would like the question escalated just direct message me and I'll make it happen.

No that ok. All the answers were great and correct. I did get my new disk and ran through the upgrade and it works great!! Thank you for all the help.
