Garmin
 

I already talked to Garmin. They sent me the STC for a P210. They don't have one for the P337. They said to use it as the Same Equipment type but in a different model for the 337. They said it would involve more paper work but they have not been able to obtain one for the skymaster as yet. They also said if I knew of one installed in the P337 that it would benefit me if I could get a copy of it.
