Sure, you can use MRA by every kind of a browser at every device, independend of Operating System.
May do it as I like to do if I prepare trips as guide for several groups: at home, I do route planning (very detailed) at a PC with big Monitor. Group members are often asking:"...how long is the distance to next Gas Station, Restaurant, Toilet?" As good group leader, I will be prepared 😉
Then I transfer the routes onto my Garmin396. I prefer on my Bike a real Navi, because of water proof, better use with gloves etc.
But I'm going to practice navigation by Smartphone with MRA Navigation App during hiking...
Later on Tour, if we decide to change some routes, I do it on my Tablet. This needs less space in luggage than a Laptop and route planning is much easier by Tablet and MRA, than by Garmin396.
Then I transfer the new route via Garmin-App "Smartphone Link" wireless onto Garmin396.
Additional benefit: traffic information will be transferred also wireless ongoing from Smartphone onto Garmin396 - and the Navi will recalculate automatcally the active route in case of detour or blocked road.
Also nice fearure: WhatsApp messages will also be displayed on screen of Navi device.
But to use this connection with Navi and Smartphone during driving, you will need to have power cable from Bike to Smartphone.
Life can be so easy 🙂
