VW Navigation System DIY Install on 2001 Mazda Miata
Fed up with my stock double-din radio I decided to upgrade.
I decide to that my next radio should be OEM looking and be also double-din. The reason behind this is that not only it will be easier to install and less prone to be stolen.
So I started to look around on the internet and found out that the VW navigation systems fit like a glove into the Miata.
I found out two models that interested me:
Although the MFD is much better than the MCD I decided for the MCD for 3 reasons:
- Price: MFD is almost double the price of an MCD.
- MFD cannot read audio CDs by itself, it can only do so with a CD changer (which means more money)
- I didn't know if I could install the system so I figured I should try with the cheaper MCD and if it went well I could always upgrade to the MFD later.
After some researching I found out the unit's pin-outs:
For the navigation system to work properly the unit must be connected to a GPS antenna.

Found the pin outs at his site:
Found this adapter cable which allows to connect
the Mazda radio harness directly to the radio.
As the Mazda antenna cable ends like this
had to buy another adapter cable:
Antenna adapter cable:
The Mazda to ISO Adapter cable plugged almost
right in the MCD need only minor cable position changes
"Mazda to ISO" Cable Changes to fit ISO
As the GPS antenna comes with a magnet it was simply
placed on the metal bar behind the passenger airbag.
Everything plugged in and ready to go!

Unfortunately I got the wrong navigation
CD and this is all I get for navigation.
It turns out there are two versions of this navigation unit. One version was fabricated until October 2000 and the other after. I found out he hard way that mine was the first version. The Navigation CD I bought is "DX" version which only works on the most recent unit.
Haven't plugged in the speed signal cable yet.The miata has no speed pulse source in its radio harness so I had to investigate where to find it.
The guy that sold me the adapter cable told me that I would find the speed signal for in the engine control receiver, behind the covering in the passengers feet area. It is the white/black cable leading out of the bottom row of the middle plug.
Will try this on the next weekend.
