What satnav still works with google maps

[suffolk009]

Just back from an epic European road trip. I need a new sat nav.

The one thing that will sway the purchase is finding one that I can plan a route using google maps and then download that straight to the sat nav.

I tried with my ancient Garmin and some third party software prior to the trip, but couldn't get it to work.

Somebody has suggested that I need to use an Android instead.

Any help or advice very gratefully received. Thanks in advance.

I use a modern Garmin along with tyretotravel.com & it works perfectly for me on bike trips through Europe.
You need a sat nav that can store the routes, some store 10 others can store more, not sure what Tomtoms can do.
