Greetings to all forum writers, with a zumo navigator 660/bmw I have this problem:
it do not charge the battery, I tried to replace the battery but not charging, while the same battery on another device has charge.
On the diagnostic screen shows the message NTC fault and a negative temperature value (but this does not about the battery).
If I proceed with the diagnostic test, the test detects a failure on the "splash".
There might be some connection with the fact that this zumo was recovered after an operation to recall fw? (formerly bricked)
