FS: Garmin c320 in GPS technology and devices Posted October 13, 2008 I have a used Garmin c320 that is in excelent condition. I have been using it for 1 3/4 years now and am upgrading, so I am looking to pass this one along. It will come with the software and a 128MB SD card and all the cables and car mounting equipment that were packaged with it (the suction cup on the window mount shows signs of use but still works well). It's truly a good unit for in-car use. I can't remember exactly what I paid for it but it is selling for $190 on Amazon and I would be willing to consider any reasonable offer. Thanks.
