Speed limits and alerts (UK)

[placetobe]

I've joined the i3 cult, helped very significantly by a friend who will probably notice this thread. 2018 with REX, basic model.

The BMW navigation is ok, but I really miss the speed limit info from Google Maps. From researching a bit (including on here) it seems fairly clear that you can't get the iDrive display of the speed limits if you don't have the hardware (Drive Assist?).

I think my options are:

1. Drive more carefully and pay attention to road signs. Obviously a good thing.
2. Use an app with audible alerts (e.g. Waze though I've heard the alerts are flaky). I'm on Android, which makes this harder (I don't want the expense and faff of trying to get Android Auto working). I have an old iPhone which I could probably get running, though.
3. Buy a dedicated device, e.g. an Aguri or Snooper dashcam with speed alerts. But these require manual map updates which would also be bit dull.

Has anyone else in the UK recently gone through this process? Where did you end up, pun intended?

My i3 didn’t have either Apple CarPlay or Android Auto fitted when I bought it, so one of the first things I did was to have an aftermarket unit fitted under the rear seat which gives me both.
