Hello Together, I recently had the AVIC-F900BT installed in my Golf+. I, too, put the exorbitant charging times into my neck. Since then, I have been thinking feverishly about how to save this scenario, as the device itself is quite usable. I am following the following approach: coupling with central locking. If (by radio key) the thing is unlocked, it should go up. When closing it down. Is in my eyes the best solution, because the device then has enough time to drive up (the remaining meters to the car, then take off the jacket and put in the back, get in, fasten the phone in the holder,…). The danger of battery discharge is m.E. also not really high. In addition, I let myself put a switch in the dashboard. Keep up with the information on how the thing went out and what the workshop required for it: / By the way: Have the update 1.002 installed. But don’t look at any point, it’s a good effect.
