Thank you Phil. I need to purchase a Dashcam for a Road Project I'm working on, and it depends a lot on the GPS accuracy. The time taken to achieve the 'cold lock' and the 'lag' issues you had mentioned may drastically affect the project results. While browsing through the available dashcams, there are a lot of info in the camera modules and sensors used, but very little info on the GPS accuracy. So unless it is tried and tested by someone, I'm not sure how I can get this detail online. Was hoping someone could mention few Dashcam models which concentrates on GPS accuracy as well, rather than only using it for some default features.
