Thank you both John and Richard.. What I am trying to do is connect the cars Garmin DriveSmart 75 MT-S nav system to the cars speakers via a Bluetooth connection.
Presently I have this working by using a male-male Aux jack cable connection between the dedicated connector that comes with the Garmin Nav system plugged into the vehicles ( as Morgan designed ) female Aux plug for the speakers located in the glove box/tidy area in front of the passenger.
This method of connection works but its untidy.. too many wires. Note: This method of speaker connection was used on the Plus Six earlier cars until a MusicStream ISBT23 was fitted in cars in the factory. The Aux plug input and its associated electronics box is simply replaced under the dash by the MusicStream Bluetooth ISBT23 receiver, all sound connections are RCA plugs etc, this then connects to the under dash volume control and then back to the amp in the back of the car.
The Garmin DriveSmart 75 states it is possible to connect to a cars speakers by the Aux plug or Bluetooth.
Now I have tried in the past to use a Bluetooth receivers sound output plugged directly by Aux jack into the car speakers female Aux jack ( as above ), however, for some reason the Garmin does not see the receiver.. It will happily pair with a mobile phone, but will not see the "add on" Bluetooth receiver. The Garmin Nav also has an option to pair with Bluetooth speakers, but again, using this route the Garmin does not see the receiver. I am guessing that the Garmin pairs with a mobile phone in a Receive/Send mode, but I can not yet understand why it will not pair in Bluetooth speaker mode as the data flow must be from the Garmin to the Bluetooth Speaker ( one way only) . Unless a Bluetooth speaker connection is also two way like a phone.??
I will need to keep digging for info on this, guess I need to look up the various Bluetooth types.. I think the latest is Bluetooth 6.
