I found a real early post on ozHonda about how to remove the stereo, but all the picture links have expired and no description.

My Stereo has one channel going intermittently distorted and low volume.
What is the procedure to remove the stereo as don't know how dash comes apart to get it out and no avail manuals for the Australian model Odyssey.
It is a different dash on all the US models, so their manuals useless.

This stereo does not need any codes if battery removed.

Cheers Mike
