Bought a Xiaomi 70Mai Pro with GPS for wife from AliExpress. Easy to set up and is user friendly. Comes with wifi, so you can connect the phone to cam's wifi hotspot and playback videos. There is an app through which you can configure the camera. Need to make an account and log in for this.
WIth GPS, lane departure warning and front vehicle movement alert are activated. Video will show the speed of the vehicle too. However, this comes with a battery. Under our hot Sun, this will go kaput in a few years, like the battery of my DP100 did.
Needs to be wired. The cigarette lighter adapter now comes with 2 USB outlets. So it doubles as a phone charger port. No idea about local agents. Try buying one during Ali sales. Cost me just under 12k for both camera and GPS unit.
