The Whistler GPS module for Pro-3600 expands the capabilities of your antenna and laser detector. It features a built-in compass with voice prompts that let you know if you're headed north, south, east, or west. It displays your speed in either mph or kph and will even warn you if you're traveling over the speed limit. You can easily update the unit's camera database, which indicates the location of red light and speed cameras. You can also manually add up to 1,000 locations that aren't in the database.
