IMPORTANT - It has recently come to our attention that ALLDATA Mobile will be unable to connect to a vehicle using an OBDII connection device after upgrading to iOS 11. If you plan to continue using the OBDII vehicle connection, we recommend waiting to upgrade to iOS 11 for the time being. We are currently working to provide a permanent solution as soon as possible.
