Re: Upgrade Speakers and Headunit

Maybe you can search ebay for the tool if you have the make/model to search for a install manual/download, or maybe remove the surround covering the locking mech and work out what is holding it.
I've got an Alpine head unit and I use a small screwdriver to raise the securing pins either side
If there are holes then a mini sized posidrive screwdriver or two and a bit of wriggling should get it out.
Good luck.
