Purchased the Spark Nano 7 with the intent to install in a personal rental vehicle at a later date. I didn't know that they automatically start charging you at 3 months at a time once you purchase the device with no authorization. You have to navigate to a completely separate page to get this information and it is not forthcoming.
Very unethical business practice that preys on people not navigating to a small tab amongst several other tabs. BUYER BEWARE!
