OK so I just got my FTM-350AR and the FGPS-1 module. Tried to insert the ribbon several times but the GPS display option fails to show up :headbang. I finally gave up and decided to give YAESU Amateur Tech support a call. To my surprise they were very helpful. The guy said if there are any creases or the cable bends in any way the ribbon is probably shot. For those who have issues with the cable here is the part number of the little ribbon: T9207421 and it costs $0.76 cents. They will ship it priority mail (5$) so your not paying $30 for express shipping. I ordered 3 just to be safe
