LMS 332c GPS question

Does the LMS 332 have an internal antenna? If not will the 3000 one work or does it have to be the 2000? Thanks.

I had that unit on my boat. No internal antenna on mine had to use that white hockey puck. Ill check and see if it has a model number on it or at least get a picture for ya.

According to the Manuel it takes the 2000. From what little I could find the 3000 should work also. Might need a adapter cable.

Any Lowrance GPS will work, but 3000/4000 will need an adapter cable. The 2000 will work with a blue NMEA cable which is what the 332 uses.

Thanks, you guys are the best.
