On occasion, a map can appear in your Accessport that is "greyed out" or not selectable. This can be due to several reasons:
1. Vehicle Lock - the map may be for another model or year of vehicle. Re-download the proper model and year version of Accesstuner Race.
2. Serial Lock - the map may be for a different serial number Accessport. Verify the serial number matches in the About menu. Re-download Accesstuner Race or contact your custom tuner.
Accesstuner Pro also has the ability to lock maps for a specific serial number or vehicle and they can not be opened in Accesstuner Race. These maps can only be unlocked by the original tuner (their IP is protected).
