trying to add depth finder to a gps276c

[forplayboat]

Does anyone have experience with the Garmin gpsmap276c? In the manual it says you can add depth capability but does not tell you how to go about it. I have looked for info online but cant seem to come up with anything. Any info would be appreciated. Thanks in advance.<br />Jim

I just looked at the product page, and do not see anything about adding a depth module, like the GSD20.<br />here is the link to what the GSD20 works with.<br /><br /> http://www.garmin.com/products/gsd20/#
