GPS/Depthfinder using existing transducer or mounts?

[eastcoastboater]

Anyone have a recommendation (or know of an existing thread here) for an aftermarket GPS/depthfinder that would install in the place of the existing transducer mount of a 2009 232 Limited? Though capable of repairs/upgrades, the thought of boring new holes through the transom and 5200'ing the transducer is something I'd like to avoid if possible.

I've gone through much of the prior threads re: Simrads/Raymarine/Garmin/etc. and haven't seen anything definitive on this so definitely would appreciate any thoughts or guidance!
