I purchased a boat that has a Garmin 2006C but was told I need a GSD 20 to be able to get depth contours. Is this accurate info? and if so I am now looking to buy one if someone has one they would like sell.

Since Garmin just introduced the new GSD 24 I'd bet you'd have no problem buying someones GSD 22.

Correct, the GSD20 was what these units used.

Here is the Manual for the 2006C

You may have bought one already but if not, I have an unused one in original box, if interested.
