I have update once when I purchase Alpine map update SD card early this year, when I log in the Alpine website. They only have update on W910R(Euro version) I even try download update from W910R and put SD card in my W910 US version. It do update itself. But I cannot update or load my may since I update from Naviextra. I contacted them and receive one feedback ask me to reset my unit. No luck. Send couple reply to Naviextra no feedback. I feel so stupid that spend $100 to screw up my unit. I try your solution download autorun.rar unzip and put SD card in my Alpine but it do nothing. Weird things is after I update my map from naviextra my Alpine do trying to update for few second then back to ALPINE logo screen and stuck. Seems like a software issue.
