Unlike other sat-navs, Motorola's devices don't come with integrated mobile data connectivity. Instead, you must pair the TN550 with your mobile phone over Bluetooth. However, this won't require your phone to have a mobile data plan with tethering enabled, because the Motonav merely places a short voice call to obtain its information. So any mobile phone with Bluetooth will do, and any call contract too.
The remaining four Moto Extras also get their information via short mobile phone voice calls. The Fuel Prices system downloads the costs of petrol for garages in the local area, and lists them in order so you can head for the cheapest, although you can also list them by distance or A to Z. However, you can't find petrol prices at an alternative destination, making Motorola's system less flexible than TomTom's.
In contrast, the Weather service lets you look up forecasts for your current location, or any other city or postcode. You can then browse a five-day forecast, although no hour-by-hour detail is available. Like the Garmin nuvi 1690, the Motonav TN550 also has the ability to look up airline information. Flight Info lets you search for airline and flight number, and then tells you whether the aircraft is currently on time and provides the ability to navigate to the appropriate airport.
