Kelly, This does not solve the question but it might be a short term fix,  try (The Marine Connection Liquidators, 772 465-6460) they buy out marine parts suppliers and salvage wrecked boats, I purchased a new old style Tankwatch panel from them 2 years ago and a new Garmin remote control for a 5212 MFD this year, that remote had been out of production for more than 5 years.  Their price are very reasonable.
