The Nav-Cam will alert you to all types of speed cameras. It does this quite effectively though it does take over the screen with the alerts. A six month subscription is included but after that you need to pay a subscription fee. As you’re driving you’re directed by a rather harsh sounding female voice. It’s clear and reasonably loud, though it won’t compete with a loud stereo.
At the bottom of the screen you’ll find an icon with three cars on it. This is the Traffic Message Control (TMC) function. This is an FM receiver that picks up traffic news braodcast from radio stations. This information is integrated into the route planning to automatically reroute you round traffic. The licence to receive this information is free with the device. When I was driving on the M25 it claimed that it had picked up 85 incidents but none were on route so it didn’t redirect me.
It sounds marvellous but in practice you need to be driving through an area that can pick up the TMC signals. Also, to pick up the signals you need to connect the supplied aerial, which has to be attached to the windscreen by two sucker pads. This plugs into battery pack, which contains the TMC reviewer. It means having a spaghetti junction of wires in your car. It’s ugly and inelegant and you won’t want it.
Other bugbears are the home button on the right. This looks like it will take you back to a default navigation screen but in fact it dumps you out of the navigations software and takes you back to the start-up screen with the pointless MP3 player and photo viewer. Beneath this is a button that when pressed sets your current location as a home location so that you can navigate direct to home with a press on one button, which is admittedly handy.
Overall, I have to say that I really didn’t enjoy using the Nav-Cam. It’s a solid looking piece of hardware but the interface is somehow more confusing that it initially looks, it’s slow and to use the TMC function you need to have wires trailing all over your car. If you want an affordable GPS device then you’d be far better served by a TomTom One. You may have to pay extra for the camera alerts, but it’s a cheaper device to start with and one that’s far superior to use use.
