@GoofIsbest,
That is why you have only problems.
It is not made for a Head unit.
Go over to the TomTom forum and see how many user's who have tried to get this to work on a head unit and have one problem after another.
Along with TomTom Go the same problem.
It does not matter what Android version you are using it will not work.
I do not know if this is an after market Radio.
If it is it came with IGO or Copilot already installed on it.
You will find no where that it said it is comparable with TomTom GPS apps.
TomTom supports in dash GPS on many cars but it comes pre installed on them.
You can check here for which cars come with TomTom GPS installed already.
