Don't do it

I do not trust them to track a tree that is standing still never mind a vehicle. I have been with them for a long time and always had problems, and couldn't cancel because I signed a 3 year contract had to pay but never got the service they say you would get and had the early warning system, not sure why its called that as they should call it the no warning system. I canceled now and you should give a month notice and I'm fine with that, so I logged in the app this weekend and and my car was taken off the app so I called them today, so when you cancel the month notice you can't use the app but they do still "track" the car so you yet again pay for the full service and month but can't use the full service.
