I want to get one of these so I can have nav in the car.
I don't care to swap out the factory HK headunit in my Outback, but I would like the bluetooth to work.
How does the bluetooth wiring work? Since my car uses an external amp stock (with line-level-inputs), how would you all suggest I wire it up?
There's a "mute" output it looks like from the screen.
I'm trying to add bluetooth though, not remove it.
The 740BT is bluetooth ready. So I can pair my phone with the screen. Trouble is, outputting the audio from my phone call. The screen has a "mute" line, or so it seems, and it also has L&R outputs.
My car, a 2009 Subaru Outback 2.5XT, has a Harmon Kardon stock stereo that uses an external amp (which is fed by line-level input).
Would it be reasonable to send the "mute" signal to the headunit (simply T it into the stock mute wire from the steering wheel control), and then plug the L/R wires into the line-inputs on the amp?
Or would that not work?
I don't intend to remove the OEM radio, simply add this screen and a NAV unit to it.
Will it work?
