I use it on my motorcycle in the US, but there are some major pain points.

I have a Bluetooth headset in my helmet, so I can hear the directions... which are usually close enough. But you still do get some occasionally confusing voice prompts that - without the screen to glance at - may lead you to a wrong turn.

I do have a handlebar mount I've resorted to on a few occasions, but as others have noted (a) the phone can overheat, (b) subjecting a $500 device to the vibration and chance of falling is not ideal, and (c) I've had the acceleratorometer actions kick in unexpectedly, leading to the phone battery dying faster since it turned the LED flashlight mode on.

That said, I have only one serious complain - the opt-out-of-route-change that they've made the default is a huge issue, and I really wish there was a setting to disable that. If I've gone in and picked between a few potential routes, having it decide a different one is faster and that I'll need to press a button on screen to stay on my preferred heading ends up leaving me off course and/or on the side of the road digging my phone back out.

(And before someone suggests voice commands to fix it... that's not a workable solution. While the helmet cuts down noise, it doesn't eliminate it, and I have enough problems with voice recognition that I leave it permanently disabled.)

I have a lot of the same issues. Bluetooth headset turned up to almost max + foam earplugs works reasonably well, as long as I already have a good idea of where I'm going. Handlebar mounts work fairly well, but putting the phone in the sun in Arizona during the summer often leads to it turning off. There's also quite a few reports of phones either flying off mounts or camera lens/focus dying due to the vibration.

In the end, I normally leave the phone in my pocket, make due with voice alerts, and leave a few minutes early so I can safely miss an exit without panic. The last thing you need on a highway filled with texting drivers (completely legal in AZ) is to be distracted and making multi-lane changes at the last second.
