GO Supreme 6 connection pin worn
The other connection pins are gold though this pin is silver in colour and uneven when magnified.
1. Would metal sanding paper the connection pin even help or the device cannot be repaired?
2. Suggest another alternative mount where the USB cable can be directly input into the device rather than the mount (avoiding this worn pin)?
3. Internal battery not holding it's charge very long now.
Suggestions besides a full replacement is appreciated.
