Just bought a Mazda CX 5, w/Tom Tom GPS, but it has no sound coming from device.

SOURCE: Tom Tom one just comes on and then says that there is no GPS devi

It "might" be that your tomtom has lost its position due to you moving countries. the TomTom stores its last position so each time you switch it off then on again it can find the satellites it had before quickly. Because you have moved a long way ( on the aeroplane ) the TomTom now thinks you are still in America so it's looking for the satelittes over America rather than over the UK.
I would try this :

• Press the reset switch through the hole at base of tomtom ( 1 quick press is all you need , dont press too hard , you should feel the switch click as its a tactile switch )
• The TomTom has now had a hard reset
• Go outside in a location where you have a clear view to the south . ( preferably a clear view from east through south and to the west )
• Switch the tomtom ON
• Make sure the tomtom has a clear view of the sky and the top of the tomtom ( its antenna is in the top ) is unobstructed.
• Tap the screen just above right bottom ( where you see the signal bars )
• The next screen shows the battery state and some bars on right side
• Tap the bars
• You should now have a bigger screen with bigger bars
• The bars are each channel your tomtom can receive satelittes on
• Wait about 3 to 4 minutes and see if any of the bars are GREY
• Grey bars shows you are receiving satelittes ( but signal is week )
• Blue bars show good strong signals are being received
• It may take a few minutes to lock on ( fingers crossed )
• If it does have a lock ( at least 3 blue bars ) your tomtom will remember and store these satelittes so next time you switch on it will go straight to them quickly and lock on .
• Your problem will be sorted.

if you dont get any bars at all then it's likely your tomtom has become faulty in the receiver or antenna section and will need proffesional repair . Rare but It is also possibly a files / data fault on your SD card . In this case if you made a backup of the card , you will need to revert to that and reinstall the files to the SD card.

GOOD LUCK

Tap "Set clock" button to select the type of clock that is shown and set the time.

SOURCE: TOM TOM GPS Updates

That depends on where you got it and if the documentation for the updates was in the box.

Usually the answer is yes.
Those from Tiger Direct do.

I have used it before now with few problems.

Couple of times I have had to talk to them but they have always been good and given me a code or new code to get the updates.

Reset it via button at rear, in a small hole...use a straightened paper clip. Then you must re-setup all again.
