What a great pity you have decided in the view of environmental issues, to stop supplying the suction cup base. As a two car family we could and did take the dashcam with us regardless of which car we used.
The cynic inside me says you didn’t reduce the price, and now you want extra payment to get the suction base. You’ve already stopped suppling the dust cover, what will be next? The second stick pad? (Which I still have).
I have no gripes with the dashcam, I think it is a wonderful bit of kit and I have had no issues at all with it (except my own stupidity and failing to read the instructions on occasions)
But what I would ask , if and when the 532 version comes out , you retain the the same fixings for mounts, the same socket connections for rear cameras, so that some cost savings on environmental issues can be passed onto the customer. So there is no need to change the rear camera or the front fixing method.
