The Idiots guide to replacing a stereo in the NB8B

Introduction:

I decided to install the radio myself for the following reasons:
1, the last time I had a head unit installed the dash was butchered. Remember radio installers get paid by the unit, not by the hour. Simple economics dictates that they will take shortcuts.
2, I wanted to save some money.
3, I wanted to learn more about my car and the audio system in it.

This is called the idiots guide, well mainly because I had no automotive repair skills or knowledge.

Requirements

One new Stereo (kinda obvious eh?)
Mx-5 to OEM Wiring adapter Harness (You don't have to get the harness, but life will be easier both now and later down the track)
Head Unit to OEM Wiring adapter Harness (You don't have to get the harness, but life will be easier both now and later down the track)
Replacement Fascia (Highly recommend Metra Part 99-7505 (MAZDA MULTI 1994-05) it matches plastic colour of the HVAC controls and it almost matches the texture)
1 x Philips Head ScrewDriver
1 x Flathead screw driver
2 x Ford Radio Removal Tools, or substitute coat hangers, nails, allen keys, or a friend who knows what they are doing.
Upgraded the security recently on your 5?


Part 1: Preparation

Put the roof down to give yourself more room. (Only if applicable)


Empty out cup holders, storage box, cubby holes of unnecessary items.


Eject any CD's from your Stereo. Hard to get them out once the power is off.



1. Use a phillips screwdriver to unscrew the two screws in the storage box (by your elbow).




2. Unscrew the Gearknob




3. Next, pop open the covers on the two screws on each side of the console by your knee. Use a phillips screwdriver to unscrew the two screws.




4. Pry the window switches up with a thin, wide screwdriver.

5. Disconnect the power connector on the window switch unit and squeeze the tabs on the black connector anchoring this cable to the console to release it.



6. unscrew the screw beneath it.



7. Lift the console at the front, open the storage box, and guide the boot and petrol levers through the rubber flap as you pull the console forward.


Now you can remove the trim surrounding the radio and HVAC controls. Here's how to remove the trim:

8. Unscrew the two screws at the bottom of the trim.



9. Now pry the surround out, starting from the bottom.


10. When all the clips have released, unclip the lighter power connector.


11. Now set the surround aside.


Part 2: Head Unit Removal

Now here's how to remove the head unit:

1. On each side of the radio are long covers that look like part of the radio face but aren't. Use a narrow flat screwdriver to pry these off from the bottom and top.




2. When they release, you will see 5 round holes on each side of the radio. You should use two sets of \"radio puller\" tools to pull the unit out, but if you don't have these, you can use 8 nails. Just stick them into four holes on each side (skip one of the two that are right near each other) and the clip holding the radio in place will release.



3. Then pull the unit out. It will come out a few inches and feel like it doesn't want to come further. Just pull harder.

4. The whole thing will come out and you can unplug the antenna and the other connections. The connection bundle is released with a lever on the bottom.

Part 3: Installing the new stereo:

1, Read the manual for the new stereo, if you haven't already.
2, Re-Read the manual, you would have skipped or missed something important.
3, Connect the Mx-5 to OEM Wiring adaptor Harness, be careful!. (I managed to bend the aerial pin, and had to straighten it and try again)
4, Connect the Head Unit to OEM Wiring adaptor Harness to the Mx-5 to OEM Wiring adaptor Harness. (I trust you ordered this)
5, Plug the Head Unit to OEM Wiring adaptor Harness into your new stereo. (I trust you ordered this)
6, Plug the Antenna Lead into the antenna socket on your new stereo.
7, Test the system to make sure it is fully functional.
8, Install the Metra Fascia Kit to your requirements (instructions can be downloaded here:

http://documents.victorytechnologies.co ... 9-7505.pdf)

Finally reinstall the interior in the reverse order that you took it out. (Makes Sense doesn't it)

Here is what my stereo install is looking like, I am waiting on a cable to link iPod to Head unit so haven't fully installed head unit yet.

Thanks Incognito,
That is a very comprehensive guide. Good work!
Mind you, those fore-arms in some of the photos look vaguely familiar??

Nah, good stuff mate, the new headunit looks sh!t-hot!!!

[Boags]

I saw beer and smokes but no mention to this in your guide... Is brand/strength important?

Boags

PS - GREAT WRITE-UP!

I think that incognito has actually given up smoking.
Maybe the stress of the install
(see how long he lasts on patches.......)

There is only one person I know that is that anally retentive. Great job though and your reseach has obviously paid off by making the install really really easy. Well done. Now what am I and Freddy going to do with our spare time????

Who are you calling anally retentive?

You and the rest of the Victorian crew can do what you naturally do on a Thursday night!

By the way, why isn't this a sticky?

Nice write-up and pics, but are you sure part 1 is neccessary. I seem to remember from my NB8A that I didn't take out the console.

I'm doing an install this w/e and I've just pried off the two long covers of which you write with a plastic butter knife, without removing the console or the surround, and it looks like the OEM H/U will slide out without interference.

Will let you know how it goes.

Cheers,
Alf

It's not necessary, but it helps a lot. And considering it isn't difficult at all to remove the console, it's worth the extra 10 minutes it takes to take apart / reassemble it to have the easy access.

Yepp, had the old one out, tried the fit of a new HU, and put the new one back in in under 10 minutes. Made the tools to depress the springy thingies out of 4 bits of bent wire coathanger, perfect. All without pulling out the console.

Pulling the glove box out provides easy access to the rear of the unit (for a double jointed, anorexic piano player).

Cheers,
Alf

Did you get new speakers aswell? If you do can you do an idiots guide for that too?
