I have had nothing but issues since I got this devise, multiple times even after blowing clear would not connect to my starter. you have to lie in order to get customer service( say its a lease issue) but most of the time they still could not help me. they don't tell you a requested check of the devise will cost you if they do not find anything wrong (which happened) even though the devise was not working properly. I have gotten run wire codes and still don't know what that is. In the last month Ive gotten 2 lock outs when I went to my car in the morning. After major issues and a bad review I finally got help for original issues but have since been ghosted ( will not return text and emails always show as "full". And I volunteered for this! shoot me now.
