New, still in bubble wrap, with tags on wire. To my knowledge, never used (and not a refurbished unit). I got it when I bought a replacement Street Pilot GPS and never needed it (my original antenna on my bike is still going strong, so don't need this spare - figure someone else can put it to use!). Mounting flange not included.
"The GXM 30 is compatible with the Garmin StreetPilot 2820 and 2730, StreetPilot 7200 and 7500, zumo 550, and GPSMAPs 376C, 378 and 478."
$125 includes CONUS 'Priority Mail Box' shipping. PayPal preferred. I can send 'proof of life' photos of my actual via email, but it looks exactly like the one below:
