What is the easiest way of providing a satnav connection to a TC

I placed a black USB power outlet into the dash masking board, wired to the regulator. Hidden from view, easy to use. Suction cup device holder to the windscreen. I use my iPhone instead of a satnav unit.

I’ve done the same.
An iPhone with Google Maps or Apple Maps is better then any SatNav I’ve used.
Sat Navs require updating. IPhones or Andoid phones get map updates with most system updates.
