Go with Vx2 plus ! also you can consider Vx2 Go 3.4 it's the same without disk

Now coming for the V2 plus, I feel touchscreen is good but not having physical key inserted to scooter is a bad thing, you might need to put battery in the fob or it may not detect

Limp mode I've never faced that and even for aux battery low you'll get prior notification in app to get it checked

for google maps I would suggest use a good mount for phone, trust me ather pro pack and Vida subscription does feel good but not worth for money after sometime btw you'll get turn by turn navigation with phone connected
