I recently had to switch to another phone as old apple phone no longer worked with dash command.
and was unable to get newer apple se phone although not new to link up with PLX devise in the car.
of which I believe drives the blue tooth signal.
Any suggestions?

 

You can’t do what now?!?

if you’re using an iPhone, I believe you have to connect with a WiFi OBD adapter. Dash Command works fine on my iPhone XS with a generic WiFi adapter.

 

I am probably using a wrong setting to link to the PLX signal just have not figured it out yet?
dash command is not connecting.
previously I had a direct connect from phone to car for power & audio together with this they are separate wires.

 

I run dash command with no issues on current iOS with the veepeak bluetooth adapter that I purchased from ecs tuning.
