Roady xt when i turn it on it works but when i start my motorcycle it says antenna i bought a new antenna and checked connections an still the same

yes. Just plug in the antenna from the XT base into the Onyx base, plug in power and activate!

one of 3 things, either your antenna is not insight of a skies view to receive the signal, or its wire is broken at the antenna, but if you remove the antenna connection frequently it pulls the center wire out of the connection on the end that fits into the radio when its plugged in push on the conductor at the back of the plug and see if this helps,alos if connection is loose take a safety pin and carefully between the outer plug case ans the ground fingers around the center pin push these in so you get a better ground, and lastly try another substitute antenna, I have re-soldered my connections numerous times to fix this issue, delphi doesn't make a very rugged product, good luck

if you plug and unplug your antenna connection to the receiver a lot it loses the ground(shielded) line connection, if your lucky you can take a safety pin and CAREFULLY bend the radios 4 outer shell antenna contacts inward to make contact with the antenna connector, if its the plug on the antenna,try pushing wire in toward plug connection to the radio...delphi never had much for life on any external products that fit their XM radios but when you need repl parts boy are they waiting for you, and they got them

I had the same problem with my xt two years ago. I had two other roadys' at the time and they both worked with that antenna so I called xm customer service explained what was happening and they sent me a new receiver for $10. They told me that those units aren't worth trying to repair. Maybe you'll have the same luck I did. Give em a shout. Good luck.

check the antenna and see if its grounded out anywhere, like if its chaffed and grouned to the car somewhere. If not try turning on the unit outside of the car or using it in the home dock, if it does the same thing its a problem with your unit or car dock

when it reads antenna it means there something wrong with either the connection or the antenna itself, it could be the location of the antenna or the antenna is going bad. if there is no obstructions on the car blocking the antenna i would advise purchasing a new antenna. you can get one at http://shopdelphi.com/consumers/satradio/xpressrc/

I have the same problem. I hooked it up to a different antenna and it works

I had the same problem, it says antenna when you turn it on. It seems that there is a small wire that stays in the radio side of the socket right in the middle of the socket. This fine wire breaks off . I think there is no known repair for this. I took a piece of fine wire from a wire brush, and poked it into the socket . Had to get one that was thick enough to stay. Then I plugged the antenna into it, it worked.

I had the same problem with all three of my Roady XTs. I posted a video with directions for solving the problem on YouTube:

Basically, you just need to have the antenna unplugged when you power up, and push menu right away, then select. Not sure why, but it worked on all of my Roady XTs. On the oldest one I had to push menu more than once. Good luck!

Chances are it's not picking up the XM signal. First, contact XM to resend your setup. if that doesn't work check your antenna connections.
