I tried to do some research but couldn't find a great answer. I would like to know the big benefits to using one of these services. They poll the car every minute typically and thus keep it from entering sleep and adding onto the vampire drain. I know they both have sleep modes, but then they aren't polling the car and you aren't getting anything from the service? I have the trial for both at the moment to see if I would like it, but I am not seeing big reasons to use them. What do you all think?
