Got my Roav Dash Cam C1 Pro yesterday, I am impressed. Anker had sent me an email to do a firmware due to a date stamping issue and went off without a hitch. Uses same mount as non pro version so it was a quick swap.
couple of changes over C1 (non pro):
2K Resolution 2560X1440,
Built-In GPS/WiFi, 2.4"
Now it has a voice that tells you what is going on rather than having to decipher beeps and noises. (power disconnected, parking monitor on etc)
I will need to play with it some more to check all functions and video quality etc, but so far im happy.
I am going to play with making a mount so I can mount the original c1 on my flat rear window in my truck. Thinking just a thicker adhesive pad (or stack them) so camera can be positioned flat against glass
