Of course the alerts aren't just visual - in fact it could be considered quite a dangerous distraction if they were. You also get audible warnings, so if you're coming up to a camera van location, the Road Angel will tell you just that, and then emit a shrill beep that repeats until the danger is past. The sound is reassuringly loud, and I could hear all the alerts clearly over both Linkin Park on the stereo and the roar of my exhaust as the rev counter clawed its way to the red line. You can even set the Road Angel to increase its volume in line with the speed you're travelling, since engine and road noise both increase with speed.
Another nice touch is the ability to obtain accurate coordinates of your current location, so if you break down or have an accident you can tell your recovery company, or the emergency services exactly where you are, ensuring that help arrives as quickly as possible.
The unit has a built-in battery that will give you approximately four hours of use, a figure that I wouldn't argue with. As well as the aforementioned mains power supply and USB data cables, there's also a cigarette lighter power cable in the box. This means that you can run the unit from the power in your car, while charging the battery at the same time. It's definitely worth carrying the cigarette lighter cable in your car, just in case you find the battery running low on an unusually long journey.
As already mentioned, the Professional Connected is controlled via a handheld remote. Road Angel has been smart enough to include two remote controls in the box, meaning that if you have two cars, you can leave one in each and simply transport the device itself from car to car. The remote is small, flat and fairly unobtrusive, so it shouldn't look out of place in most car cabins. There are Velcro strips provided, allowing you to secure the remote to a convenient part of your dash, although personally I'd rather not be sticking things to my car's interior. Most modern cars come with small cubby holes for change, which will accommodate the remote nicely.
The basic Menu, up, down, back and OK buttons on the remote are pretty self explanatory. The Store button will store the coordinates of your current location and send them back to Road Angel. The Delete button will delete a user defined alert input. The Mute button mimics the button on the top of the unit by muting alerts, while the power button will switch the device off.
