I have installed two AV-30s (AI & DG). Also previously installed is a TruTrak Autopilot and a panel mounted Garmin Aera that provides NAV data (blue wire) to the TruTrak. The installer spliced the 232 wire from the Aera to provide data to the AV-30s and TruTrak. I now have NO GPS displayed on the TruTrak but the AV-30s work 4.0. Is a three way splice of a data wire OK?
Any ideas?
