Previously I would use Navigon in conjunction with Blindsquare to benefit from GPS navigation with IOS.
Now I seem unable to get this assistance from Navigon after updating it and it's maps.
For navigation the app is compatible with some navigation apps.
On this page we will explain how to update the music CD data (Gracenote database) for your HDD navigation system. Save the decompressed data from step 4 to CD-R or CD-RW media. To display file extensions, open "My Computer," click the "Tools" menu, then select "Folder Options." Click the "View" tab and uncheck the "Hide extensions for known file types" option (Windows only). *If the vehicle battery is low due to cold weather, the battery may become drained during the update. Power up the MMCS and display the map or AV screen. *Screenshots may show items that are not displayed in some vehicle types. When the version update is completed, a message reading “CDDB update has completed.”* will appear on the screen.
The procedure is outlined in the following illustrations. *The screen shown appears when English is selected. After decompressing, save three files with the extensions ". *There are two datas: "Data1""Data2",and these cannot be saved in same CD-R or CD-RW media. To prevent this, turn off any devices that use the battery, such as lights, air conditioner, etc., and perform the update with leaving the engine running. The ‘AV MODE Selection screen’ shown on the right appears in the 2007 model. A version update progress screen will be displayed, and the update will begin. The screen will automatically return to the AV MODE screen. When the version update is completed, a message reading “CDDB update has completed.”* will appear on the screen.
Thanks, but that still didn't work for me because it kept refreshing or maybe it's because I don't have the patients for it lol.
I think I will email the developer as this seems to be a bug that's been there for a few updates now.
