I received an email from Toyota this morning announcing the 11.1 DVD available for the new price of $169 MSRP. It said to check with your dealer for update info for the differences between 10.1 and 11.1. I was at the dealer this morning for a brake fluid issue and asked for the update info. He emailed me first the Gen 4 version and then resent the correct Gen 6 version for me. Find these attached. Does anyone have the update info for the differences between the 9.1 and 10.1? I do not see enough differences in my area to warrant purchase of the 11.1. But I have not seen the info on the 9.1 to 10.1 differences. The combo of the two may be more worth it.
