I am trying workaround the lack of Aux port in GLS450 using Bluetooth transmitter, I have tried a popular Bluetooth transmitter from Amazon but the 450 is refusing to detect it.
Any tried Bluetooth transmitter with GLS? If yes, please share the model no?

Just use your phone. No transmitter necessary.

 

I am trying to connect Echo dot to the system.

 

Doubt it will work due to protocol incompatibility.

 

FM transmitters work on short wave transmittal and is not specific to car model. Just ensure you have the FM radio on not DAB, then just tune your radio to the same frequency as your chosen tranamitter, simple. Remember though you are limited with the transmitted band width hence the low sound quality and frequency range.
