Called PhotoLive, this taps into the network of traffic cameras around the country and lets you see exactly what they can. This isn't a real-time feed, just a still-frame snapshot every so often. But it can tell you if junctions are clear or congested, and provides a general idea of real traffic load. You can peruse specific cameras, or set up a selection as favourites and view these as a grid, calling up one for full-screen perusal with a single touch.
It's potentially very useful, but not something you can take advantage of when on the move, unless you're a passenger. Unfortunately, you only get a month's trial of the PhotoLive system, after which it costs £3.95 a month.
You can also check the fuel prices for nearby petrol stations. Sadly, here too you have to activate before use, and there's no free trial, so you have to pay 95p a month straight away even if you just want to sample its abilities. In fact, many of the services require activation before you can use them, but some are actually free. These include the aforementioned Flight Status, and a currency converter that uses live prices between a fairly comprehensive range of world currencies.
The Telephone Directory is another unique Garmin nuLink! feature. Again, it must be activated prior to use. This then enables an extra option in the Where To? menu for a Phone Book, which allows you to search by surname and optional first name. You can navigate to an address, and it even lists the phone number, although you can't call this directly. Instead, you will have to punch the numbers into your phone manually. You can try the Telephone Directory out for 30 days, after which it costs 95p a month.
When you reach your destination and need somewhere to leave your car, Real Time Parking also includes prices with its POI information, and even spaces available, where this is supported (we couldn't find any UK lots which were, though), and whether the car park is open or closed. There's Garmin's Last Spot system, too, which saves your location when you unhook the 2320 from its mount or turn it off, assuming this is where you're stowing your vehicle before heading out on foot. You can then find your way back.
