Mute wire and cell phone bracket?

[SDGuy]

Hi,
New Mazda 3S sedan owner here. I'm going to install my full Motorola cellphone car kit that I removed from my Mazda truck. Does anyone have a suggestion for a mounting bracket? Is this one any good?:

Also, is anyone aware of the color code for a mute wire behind the radio (a wire that mutes the radio when grounded). The wire labeled "L" says "tel mute" - anyone know if it is connected and whether it gets grounded or gets 12v to mute?

Thanks. SDGuy

I'll answer my own questions.
1) The Panavise bracket worked fine and installs easily.
2) The pin labeled "L" worked perfectly as a mute when the pin is grounded. There is no gold pin inserted in the connector at position L, so I had to solder a wire at the circuit board corresponding to pin L. Not too difficult. Most car kits have a mute wire that goes to ground during a call - so most full install kits or bluetooth kits should work fine. The unmute is less than a second even during CD play which is very nice. That is why this mute solution is so much nicer than just using a relay to kill the switched 12V power to the radio.

As reference material, see this link for pinouts although the color codes mentioned for the various cars are nothing like the MZ3:

Here is a great link for color code and radio removal in the MZ3 although there is no need to remove the top vent:

Hope this helps others. SDGuy

I don't think you can get phone mute without the full install car kit. I'm sorry but I didn't take pics. The pics at the soundomain site above show how easy it is to get the radio out...
