Review on Garmin 010-12199-04 Power/Data Cable, 4-Pin 4Xdv/ - Enhanced Connectivity and Versatile Performance by Amy Price

I received the power cable with the wrong connector so it doesn't fit/work with my Garmin Echo Map Chirp 74SV. How do I return it and get a loan for it? I need the right power cord. The chord description on the bag it came in says 7Xsv and a few others. Does not fit 74SV. I do not want to return what I received and intend to purchase the correct one from West Marine.
