Thanks Does this involve going into testmode? (never done that). Or can i change a file in the firmware and then flash the unit? Are these KM's, miles, feet?
Oh and what does the first one do (strange units, 8 feet?) (approach_beep_distances="8,16,24" ;("8,16,24")?
I don't mind the unit warning me for speedcams at a fixed distance if that is possible.
