The other map screen addition is the One Click Menu. A single touch to the map screen during navigation calls up icons for three Points of Interest (POI). Clicking on one reveals a tabbed menu listing nearby POIs of the chosen type, with the other two in the remaining tabs. By default, the three categories included are petrol stations, restaurants and parking, but you can configure these to be any of the 27 categories Navigon uses in its main POI database.
The parking One Click Menu option overlaps with Navigon’s Clever Parking, although the latter only appears when you approach your destination, whilst the former is always available. With One Click Menu, you can detour for food or petrol any time you like in the middle of a journey – although, of course, your passenger should be the one operating the touchscreen unless you pull over first.
The hands-free capability of the 40 Premium has been upgraded to what Navigon is calling Bluetooth 2.0, although this is in comparison to previous Navigon implementations, not Bluetooth v1.2. The main enhancement here is the ability to link to two mobile phones simultaneously, which will primarily be useful if you have different handsets for work and home use. You will then be able to make and receive calls from either using the microphone and speaker in the 40 Premium, as well as accessing their phonebooks and recent call listings, although we had trouble getting the latter to work properly with an iPhone 3GS.
The 40 Premium also supports Navigon Sightseeing, a feature first seen in the 2510 Explorer and allegedly “Inspired by MERIAN Scout”, the in-context tourist information company. This is essentially a quick way of loading a pre-created route of waypoints. However, the route has a description and each waypoint does as well, including useful information like phone numbers. So you can plan a trip encompassing key landmarks in an area. Unfortunately, the 40 Premium only comes with a single route in the Lake District. If you want more, you can purchase over 100 routes across 14 European countries for £15.
Other than this, the 40 Premium hasn’t changed an awful lot over its predecessors. Traffic updates are included, and these are provided via the RDS-TMC system so arrive on the back of FM radio signals, which are detected using the car power adapter. You can either browse a list of incidents available from the Options menu on the main screen or use the traffic icon, which pops up within the map when traffic is detected on your route. You can set up the Navigon to reroute you automatically or merely inform you verbally that a better route is available. You can then click through to see how much time the alternative route could save you, and then again to see the details of the traffic on your route.
