I have an old Starmate that was working fine but now when I hit a bump in the road or someone closes the door it shuts off. Sometimes comes back on, sometimes I have to turn or twist the power cable connecting to the radio. Use the radio in two cars and it happens to both.

Do I need to open the unit up to see if the power connection is bad? Can I open the radio up? Have you seen similar complaints about old Starmates?

Thanks for any help you can offer,
