@mafian,

Why not trying to linkup with your smartphone to your car radio.
As you did not tell anyone what type of car radio you have in your car you just might be about to connect with a USB cable to the radio.

If not just use your smartphone for your GPS.....
Unless you are ready to replace the car radio with an after market one you could just be out of luck.......


@xanderh,

TomTom GO has been prone to have all kinds of problems with car head units.
The TomTom forum is full of posts........
It is hit and miss that any users get it to work 100 %.

Plus TomTom GO is now dead and no longer supported.

It has been replaced with TomTom GO Navigation - GPS Maps & Traffic Alerts and that is not been very stable.
Best if you are going to use any GPS app TomTom NDS Mod or Sygic Mod are your best bets.
