I should add some additional bits and pieces.
The unit comes with maps - for a particualar local area. So the Zumo XT LM for USA and the Zumo XT LM for the UK will be the same hardware, but will be configured differently.
LM means Lifetime Maps. But only for the region in which it is sold. USA Zumos will have maps for the USA. UK Zumos will have maps for the whole of Europe. This is important if you are thinking of buying a second hand XT off the internet. Make sure you ask the question - which maps are installed on it ?
Maps are updated free of charge. They are downloaded from the internet - either by using your phone's data /wifi or by using a computer with internet access and a USB cable. You use a program called Garmin Express to install map updates and other software updates. Garmin Express is free to download form the Garmin site and free to use.
However, if you are in the USA, you only get updates for USA maps. If you want to come to the UK, then you get to pay for any additional maps that you need. And if I (in the UK) wanted USA mapping, I'd have to pay for that. Thats important for buying second hand - if you find it is an XT for a different region. You'll have to pay for the correct maps to be able to use it. And they are expensive - especially when you consider that you should have had them free.
There are some features available on the XT which do require additional purchases - but they are separate things - which require additional hardware which many people just ignore. Like Garmin Power Switch and Inreach staellite tracking.
The XT is intended to be used with a program called Explore, and when setting it up, it suggests that you have to initiate this facility.
I would suggest that you resist that temptation until you have found out how to use it at a basic level. For some people Explore is the bees knees. For others (like me) much of it is stuff that I do not want. It is easy to set up later. It is not difficult, but a pain, to disable it once it is set up.
Explore needs a Garmin account to be set up. This is free. It allows the XT to use your phone to talk to your account on the Garmin Servers. You can plan routes and tracks and waypoints on a notepad, phone or a computer and the system will automatically synchronise with your XT - so they just appear in the appropriate resource apps.
For this to work, you need an app called Garmin Drive to be on your phone. This too is free, and this is quite impressive. It provides a link between the outside world and your XT. It collects traffic info, weather, road closures, and on Android phones eaven filters the messages, emails and alerts which can be passed through to display on the XT screen. It also handles any files that you care to email to your phone - and if they are gpx files that contain routes, tracks, waypoints then you can get it to send them to your Zumo.
The Zumos handle pone calls. You put the zumo in between your phone and your headset so the headset is connected to the XT. The phone is connected to the XT. So the XT has access to your messages and phone book, and you can make calls from the XT screen.
There is no wired connection to a headset. IT is all done by BT - so if you want to here music, phone calls, navigation instructions you need to get a headset that will connect by BT. You can buy very simple ones - as long as the earbuds fit inside your helmet, or state of the art helmet units like the Cardo or Senna devices. If you have wired headsets already - like (say) an autocom - then you need to buy a Bluetooth Module to transfer the sound in and out between headset and Zumo.
The only other thing that you may need is some mapping software. Explore is free, but it provides a different solution from the one that many people want. Garmin Basecamp is old, no longer supported or developed by Garmin - but it does everything that the XT needs to produce trouble free routing. You will hear a lot of negative comments about it - mainly from people who have heard negative comments about it. Those of us that use it realise how excellent it is. And it is free from Garmin.
You will probably find this useful at some point . Its worth flicking through just to see the pictures.
