P850C and 850C are probably the same.RicMcK wrote: ↑Feb 05 2020 1:02pmKT-LCD3 upgrade?
I am confused on what I need to upgrade from a KT-LCD3 to 850C. First does anyone know the difference between P850C and the 850C? Can you "see the 850C in the sun? Next do I have to add the SW102 Bluetooth? I can't see my phone in the sun and I don't plan on using it with the bike.
Yes, 850C can be seen -- search on youtube reviews of the 850C display, it is very popular for Bafang motors, you will get feedback about your questions.
You need to choose between using 850C or SW102. 850C is the recommended one for the reasons explained on the wiki. Follow the wiki to install the firmware.
