Garmin Rino 130 Shut Down

I had the same problem; mine would shut off when bounced around too.
I used a #0 phillips screwdriver (very small) to take out the 6 screws that hold the case together, Carefully separate the face and back because there are wires that can be broken if you pull them apart too fast.
After you get the case apart, lift up the circuit board at the bottom and you will see a small blade pin that sticks out from the side where the batteries are and is supposed to slide up into a contact on the circuit board. I guess over time it starts to wiggle and get loose so I carefully bent the pin (very slightly so it would rub the inside of the contact.
So far I have tested it by dropping and beating it up a little and it seems to have fixed the problem.
Hope this helps.

I was having the same problem, but thanks to SnappyWD's tip I'm am back up and running again. I use my RINO 130 almost exclusively while riding and racing a motorcycle in the Southern California desert, so it has/does take quite a of bit being bumped and tossed around. I took the unit apart as Snappy said, but instead of bending the pin back, which is the connector from the batteries to the circuit board, I re-soldered both battery connections to the circuit board. While they looked OK to the naked eye at first, they clearly were the broken link. I have bashed the unit pretty hard now and it works as good as new! Thanks SnappyWD!!

I need a battery cover for my rino 130 whats the best place to buy one?

I think there is a problem with contacts, tray to clean the battery contacts on batteries and on the radio, try to tigth the screws of the Radio.
