Comes with a charging lead

It comes with in-car charger and mount.

Yes it does come with a charger

This does come with an in car charger, and it may be chaged using a USB port on a PC (lead included). But you cannot use the unit for map browsing when plugged into a PC (the touch screen will not operate)

Comes with in car charger, and lead to receive traffic update, and usb to computer, all in box.

The in-car charger is supplied as standard

Mine came with the incar and a USB charger. Also has the mount for windscreen and a dash ring adapter..
also has an antenna that plugs into the power cord for the traffic system.

Hi
the extension only needs to be used in weak signal areas, as long as the logo for traffic is shown, the receiver is working - Mac

The FM Antenna plugs in to the power cable and yes you need this in to receive the FM Traffic updates

Does not need to be plugged in all the time but helpful if traveling when traffic is heavy. makes it more accurate.

There is a small socket for the antenna lead in the plastic block a few inches down power lead. I have always plugged this in and found some of the recieved data useful but now always 'in time' particularly when trying to decide which way to round the M25.

It plugs into the box thing on the power lead that goes into the sat nav. Then you use the suction cups to stick it to your windscreen. Not sure if you need to have it plugged in all the time, but I suppose if you really want FM traffic reports then best leave it plugged in. BTW: If you haven't already, go to the Garmin website, and download the 'full' manual, which is far more in-depth than the quick start guide that comes with the unit.

No you can't.
I tow a glider trailer so drive accordingly to the laws of the country in force. Well, most of the time anyway:-)

no

I dont think it does change to a lorry, you can change car sizes even to walking but no lorry.

All safety cameras are covered fixed,mobile and red light

Only UK ones come with the unit. You can purchase others for European countries from Garmin.
Didn't bother myself, speed limits are shown for France, Holland, Belgium, Germany, Poland and Lituania that I know of, so assume the rest are the same. If you go over the speed limit it shows up in red. If in German on motorways, no speed limit shown on certain sections......... Fill your boots!

No, the Route Options are very limited!

Yes you can add additional stops.

When you first start your navigation, naturally, you select your destination and 1390T calculates the route. After this point if you want to add new via point you need to search for it without stopping the existing route.

When you found the new location it will show it on the map and there will be a Go button. Press the "Go" button. 1390T will ask you how you want to add the new location, as the new destination or a "Via Point".

If you select Via Point it will add it and restart routing.

yes it does include those languages, and loads more.

I dont think so. Mine seems to be the same volume each time.

There are no subscription charges for the traffic update at the moment

Need to pair it with the unit first.
Shows up on the home screen when paired.
If still no joy, contact Garmin UK
