Horrible company to deal with, all around. They will quote you one price, then charge hundreds of dollars over what they told you it would be. They bill you for charges that don't exist. I have checked with my local DMV, and the charges they list on my account, DO NOT EXIST. The device has caused serious mechanical problems with my vehicle. I have been inside a retail store shopping and came out to the parking lot, to my vehicle sitting there running, unlocked, just waiting for someone to steal it. They advised me that I might have to pay to get it fixed, but I won't know till I bring it back to the installer. I am sure they will say it's not the device's fault. DO NOT USE THIS COMPANY.
