Handing the x5 to my boy in three weeks full time. OBD tracking device to measure speeding hard acceleration(4.4 v8 if I were 17 I would be stomping it) hard breaking etc.

Anyone use one or know if it will cause problems? I trust him but want to protect. I can always just place a tracking device butmtheynare twice the price and require a subscription.

Thanks in advance. Te one im thinking about is VYNCS premium. Don't want to mess up the system.
