None of these GPS app work well with a car head units
They are not even supported by TomTom.
They are made for Smartphones.
Yes some users have gotten one of the GPS apps to work on a car head unit but in most cases it is not stable.
Go over to the TomTom forum and you can read it for yourself.
As for updates you will have to use the non patched version of TOMTOM NDS and be done with it.
Plus drop the BS about Twitter you have stated there are no updates to maps with the MOD version.
I think it is time to move on......
PS:
You can use TOMTOM NDS and link it to your Head Units too.
With the correct software. (using SmartDeviceLink (SDL) technology)
You can find that info here:
