I know, first-world problems and all...
Last year my XM radio started going out, losing a signal, then giving me a "check antenna" error. The connector always looked like the week link, I never thought a super-mini USB connector would be a good idea when subjected to conditions a motorcycle get subjected to. At the end of last year I siliconed it to seal it. After removing it for the winter to use in my Jeep, I reinstalled it, but it would only work for 5-10 minutes before giving the check antenna error. I cleaned the connections, tried all sort of pre-load fixes, but I eventually said "screw it," and bought a new-used antenna. Worked great for a day, then gave the error.
So I figured it must be the cradle. I bought a new one, and installed it. Seemed like a lot of play in the connector, but the old one was like that when it was new. Worked for 2 days. Check antenna.
Not sure what to do now, I am thinking that now that I have an extra antenna and cradle, maybe I can disassemble the cradle, cut off the connector on the antenna, and just solder it directly.
Anyone else have this issue? Use something other than the GXM30 antenna? Is it possibly the Zumo550 itself? My google search showed some others having this issue but no real solutions.
I would really hate to just buy another separate radio, as they are not waterproof, and I like it being interrupted for turn by turn directions when riding so I don't have to play around with a mixer or manually switching.
