Hi Everyone,
I recently got my hands on a 2000 Accord Saloon that's been very well cared for so far. Aside from the usual bits and pieces I've been fiddling with fitting up an Aux in to the setreo.
I've searched and searched and eventually thought I had a solution.
I have the Bose cassette deck with the changer in the boot (very handy as it means no pulling the HU out).
After some reading I found that it runs on the Alpine M-Bus 8pin system and bought an M-Bus to phono adapter and a long phono to 3.5mm cable.
I've connected it in the boot and then fed the 3.5 lead through to the front and have it secreted away reasonably nicely.
On my initial testing (radio was turned off with the cd changer selected) it all worked lovely with CD EEE showing on the display (fair enough)
I switched to FM for a short drive round. Pressing the CD button after this did nothing. It made no attempt to switch over.
Reconnected the changer and all was well. Connected the aux cable again and all fine.
With the aux setup in place it appears that switching source stops it from being able to go back to the changer input.
I suspect then that the AUX adapter is just using left, right, and audio ground. The problem being that either a signal needs to be sent back to the head unit or possibly grounded.
Looking at a pinout for the connector there are the following connections stil available:
Battery (12v constant power), Acc (12v switched power), M-Bus, Bus Ground, and Ground.
Not knowing a great deal about the M-Bus setup I imagine that the M-Bus pin is what sends back the disc and track info to the head unit.
Does anyone know if shorting the m-bus to a ground would do the trick?
If so I can modify the connector I have or make another to fit the purpose
If not my other thought is some form of Y cable/adapter feeding both the changer and aux cable to the head unit. WIthout any discs in I can still select the changer and then it's just a case of piggy backing the audio along.
Any help on this would be great as I can't find the info anywhere and don't want to splash on anything like the xcarlink kit if there's no need.
