Garmin Fusion 2018 Seneca

[HJP]

We can not get the radio (RV-BBT600) to play while driving. It will play when parked and engine is off. We can hold the Aux start and it will play but cut off when released. Any ideas?

I would start by checking the fuses on the latching switch in the battery compartment, this is common to both battery banks.

On a side note, have you kept your Gamin unit updated on the software, it makes the unit much better.
