Hi I'm trying to update my 612gw before I install it in my car. I have tried using the replay software option of updating but it just constantly says connecting to dashcam. I have options on my dashcam screen mass storage, power on or update. I have tried selecting all three but to no avail. I also downloaded the update folder to do it manually but my system will not allow me to open the bin file. I am currently using system that is running windows 7 is this part of the problem or am I doing something wrong? any help please.
