Yes you can remove it but you lose the benefit of having it. You can see the fuel and you can set the air conditioning to warm up or cool down the interior. It will warn you of its location including if it gets stolen. Mine even sent a message to say one of the rear windows wasn’t closed when the wife was shopping and when she went to look she realised she must have caught the switch when leaving the car. It was open a tiny bit and it warned us. Having said all that, mine was a pain at first and never connected properly despite me trying all sorts of things off this forum but I went to the dealer and they got one of their techy geeks (not a mechanic, an IT sort) to connect it and it’s been perfect since. I can 100% assure you, if it isn’t working it is because it isn’t connected properly.
