Just taking a quick break from enjoying my cold beer in the sun here in Bonn
My 2p as follows.
We bought a Garmin Nuvi wide screen 3-4 years ago, after invaluable help from one during Spa trip. But it's barely been out of the box.
Why?
Because, before buying the Evora, I discovered that the Google Maps app for iPhone did all the Garmin did but bundled into a device I generally always have with me. Yes the phone gets warm and needs to be hooked up to power, realistically, but if you are following a prepped route you don't even need full data coverage (apparently). Eg, I navigated our new MINI through deepest darkest Yorkshire Dales with practically no phone coverage, yet mysteriously Google Maps Nav continued working. Granted it won't deal with new on the fly route design in such situations. Which may be more of an issue for some than others
Now, however, I have Apple Carplay through the touchscreen headunit in the Evora. This means using Apple Maps. I intend to rely upon this - plus a good ol' paper atlas my brother donated last night. I've even programmed in my hotel stops as "Favorites".
I'll also be taking my excellent screen mount for the phone - a Montar - so that I can switch to Google Maps if Apple Maps gets upset.

The Montar was great for in car video at Cadwell last year too, so doubles up for that obviously.
As for data, I think Three includes France as a Feel At Home destination, so its part of my existing package in any case.
