A:AnswerHey there! If your vehicle has a cigarette lighter adapter or a USB port, you will be able to use this GPS in your vehicle. Yes, you can still use the GPS while it is charging, in fact, we encourage it! Cheers, Chelsea at TomTom
A:AnswerHi there! Unfortunately, this cable would not work with a TomTom XL 340 S device as that is one of our older models and therefore has a different cable. Cheers, Chelsea at TomTom
A:AnswerHi there,
I'm not sure on this one, as TomTom don't support Garmin products. Perhaps a BestBuy agent can help here?
Cheers!

A:AnswerHi there,
This won't work with your XXL model, unfortunately. You will need a Mini-USB cable for your XXL.
Hope that helps!
