Have read earlier FAQs over this problem but when opening System Pref. /Network the TomTom is not seen so I tried the + to create an interface but TomTom was not shown on the available list. Now I'm stuck?
My iMac is the latest model Catalina version 10.15.1 and trying to install updates on TomTom Start Device APxxxxAxxxxx (0) (20.2)
