Unacceptable behavior from 70mai! They suddenly stopped the ability for parking mode without the hardware kit with new firmware! That was nowhere stated when we bought it, this is why it has the internal battery, to be able to use it for a certain period WITHOUT the hardware kit which was only recommended for longer periods & not compulsory. But now… parking mode doesn’t work without it.
No official answer from 70mai to emails and also we dont have the ability to buy but only in aliexpress
