the cable is great and works perfectly. i paid for 3 day shipping and it took over a week to get here from the shipping notice i was emailed

Product works as advertised, build quality seems good. This cable set allows use of 12 volt DC power with any Garmin GPS that has the round 4-pin DIN connector. I purchased this cable for use with a 60CX. The 9-pin Serial connector provides RS-232 connectivity of the GPSr to other devices, typically a laptop computer. On my 60CX, the RS-232 connection is used only for NMEA-0183 communications, all other I/O is via the USB connection.
NOTE: NMEA-0183 allows your GPS to send navigation position data to devices like a Marine autopilot or chartplotting software. This cable would be a good choice for using a 60C series or similar Garmin GPSr on a boat or RV where the owner is running real-time navigation software on a PC, or wants to connect a 60C to a marine autohelm or tiller autopilot device.
This cable can also be used in a automobile or RV to provide 12 volt power only to the GPSr, without using the RS-232 connector, although there are other low-priced power-only cables available for this purpose are are less bulky.

This is fairly bulky, but it works great. I wish it had a USB instead of serial port. The connections fit securely which is appreciated since the last one I purchased for a diff't model had very loose connections.

The cable works flawlessly. I used the cable on a long trip (14+ hours) with no problems. I have also used the data adapter to provide data to an APRS beacon radio and that worked fine.
