The GPS is very important when we are driving Grab / Uber. However, sometimes the GPS doesn't want to work, especially when it is raining.

So I would like to seek your kind suggestions - which GPS is best when driving in the rain for :

- Grab

- Uber

Thank you.

I hv an old Garmin, which does not seem to want its maps updated. 🙁

But this is a good suggestion.
