Mazda3: How to keep stock clock display with aftermarket radio and dash kit
 

im going to break it down as simple as possible im may seem kinda over explaining but im going to describe every part of the install in detail....
ok you start off by always unhooking the negative battery terminal before doing anything with the vehicle electronics(disclaimer) lol but anyways you first remove the trim piece that is covering the display screen above the radio, start on the left side(driver side), this piese is only held by clips so apply moderate even pulling pressure and it will come out...than you remove the 2 screws holding the top of the radio in. after the screws are both out pull the radio strait out untill the bottom clips release than you will need to pull the bottom of the radio up and out to keep the screen at the top from getting damaged or broke. once the radio is out unplug it and, the screen, and also the screen is attached to the radio via a small clip underneath the screen taka a small flathead and stick into it pushing it off without breaking it and there will also be 2 screws on either side...keep the radio near by, your next step should be to take the aftermarket dash piece and you will neet to take a hot knife or razor knife and cut off the black piece that blocks the hole where the screen goes. once that has been removed there are 2 tabs one on either side of the bottom of the screen cut them off as well.. now you need a piece of backstrap and the following pics will show how you need to put them on

this one is on the left side:

once youu get this dont its time to reassemble but first you need to take the factory radio and hook it back up turn it on and set the screen on what option you want(avg. mpg, curr. mpg, clock ect....) it on cause you wont be able to change it without pluging in the factory radio again... but do not un plug battery after you set the screen cause it will reset it. just turn the radio power off and unhook it.. now to reassemble slide radio back in put screws back in and place trim panel back over the display and the finished product should look like this

finished look:

nice work, and nice submission to the how-to forum :)

Mazda3: How to keep stock clock display with aftermarket radio and dash kit
 

Hi, Happy new year! i need your help regarding the aftermarket radio how to keep the stock clock? i bought a radio and i want the stock clock display to be active, i want to know the wiring diagram how did you connect it? hope you cam help me. Thank you very much.

How did you wire it
 

show'd us how to install it in the dash witch im sure we all figured that out. the big question is how to wire it so it has power and isnt just a dead screen there..

Hi, first post to this forum. I've got a Speed 6, my wife has a 2007 3i.

Sorry for reviving a dead thread, but, this is exactly what I was wanting to do. But as Jaigle says, how is it wired? That is what I need to know. Further, it would seem to me that it should be possible to figure out how to wire in two switches for the "clock" and "set" buttons. I'm not good with car wiring, so, I'm not sure I want to tackle it. But, it sure seems it should be possible to find out.

I googled for dash kits, and I found some sites that claimed the Metra kit retains the stock display, but, I'm pretty sure that is false. The Metra kit for the Speed 6 indeed retains the stock display, but it retails for $200 and includes a circuit board.
