You must have been wondering why GPS is not working on the 70Mai Pro, and what is the empty slot with terminals for on your dash camera. This was my question as well at first until we got the module itself.
Upon inserting into the dashcamera, there was a feature that got unlocked, its the ADAS function, this enables you to detect cars in your front as well as lane changing when driving. This comes in pretty handy when you are on the road and I do personally recommend you to add this module into your dashcamera for added security features.
