Have a problem with the power connection on my Roady2 XM radio. When the cord is moved or the car hits a big bump the radio turns off; sometimes the plug needs to be pulled out and put back in and/or rotated or jiggled around to get it to connect again. Has the same problem with the home kit. Believe there is a break somewhere inside the radio. Is it possible to repair? If so, how? Would like to open and try, but radio does still work, so... Thanks for any help at all. Only help from XM is to replace it and they don't have those types of radios anymore.
