Apple Car Play and Roaming
Several years ago I needed to download TomTom and I needed the latest map updates if I wanted to drive from Switzerland to England or from Switzerland to France, or to Spain. Thanks to roaming I now have a much broader choice.
TomTom was good in another era, when we had to pay roaming fees. We downloaded the relevant maps. We set off, and the GPS would guide us from A to B and that was that. I tried doing the same with Waze, hoping that the entire map would be downloaded when I set off, only to find that eventually I went off of the downloaded map and I had no more information due to a switch from Spanish to French roaming on a Swiss contract. I made it home, but it showed the limitation of roaming at the time.
