In models G620T Kenwood KNA-pois single warning radars with a single "beep" which is risk to the driver as it should look at what the speed limit warning is announced. In the case of pois if they are bmp images of each type of speed.

I think it's more practical and safer for all drivers, a voice announced radar limit by which we (30, 40, 50, etc.). Or if semaphore type, pattern, tunnel, black point etc..

I hope that in future this be taken into account the safety of all. Look at the NAV screens is not recommended because of the risk posed to others and for oneself.

Think carefully.
Thanks for all the contributions.
