Hi guys, I have a couple of questions about my 998 HD:
1) My power cable started to disconnect from the head unit without any sufficient impact. I can not see a significant play or something, but the unit started to turn off frequently when I touch the cable. Seems like the problem is in connection play, because the cable doesn't look damaged. I actually found it out at home when I was exporting my waypoints. Don't know how it will work on boat, but seems like it will cause some problems and it might turn out really bad if I decide to upgrade unit software and it will turn off at that moment

The question is if I should order one more power cable just to try or if there are some solutions helping to fix the cable rigidly?
2) Another question is if I should I do some preventative maintenance of the unit connectors. One guy's unit started working really bad when his connections got rusty. Check out the photo.
Thanks a lot in advance!
