Seaching this forum reveals past issues with RSA, some of which I have experienced on my new Design, which I collected a couple of weeks ago.
I accept the sign recognition will not be perfect - and for me this is not the issue. My intermittent problem is that it frequently beeps and shows the speeding symbol, when I am just over 5/8 of the displayed speed, as if it is interpreting this in kph rather than mph. I can of course turn the beeps off, but I would like to use this feature.
Although a minor issue I note that when it works correctly, if I set the speed notification threshold to 5mph it actually beeps when I exceed 3mph - again apparently interpreting this in kph.
Before I report this to the dealer I wondered if anyone else has any insights or has recently experienced this issue?
