In summary, here is a list of all the things I ended up buying to get my stereo installed.
I think I'm about done with the stereo install now!!!!
- Scosche dash kit: http://www.sonicelectronix.com/tell_a_friend.php?product_id=36020
- Connects2 CTHMZ03 harness http://www.carstereos4u.co.uk/search/results/CTHMZ03
- Connects2 CTKENWOODLEAD steering wheel patch cable for Kenwood http://www.connects2.co.uk/c2search.aspx?catID=112 (this is obviously if you have a Kenwood radio. Otherwise you'll have to order one for whatever brand you have)
- ISO to RCA lead adapter (just ordered, haven't received this yet) https://www.secure-server-hosting.com/secutran/transactionsi1.php
- AXXESS Steering Wheel Control harness - NO LONGER USED
- AXXESS OEM Stereo Interface Harness - NO LONGER USED
- AXXESS Kenwood Stereo Steering Wheel Control interface cable - NO LONGER USED
- Lots of extension wire to extend the AXXESS T-Harness connector back to the cargo area to plug in OEM Radio for Clock adjust and to keep A/C working - NO LONGER USED
Same here, but I don't think the car's mic is that good. People have complained that the OEM setup doesn't sound that well. My Kenwood uses a Parrott setup and it did pretty well in my other car, so I'm OK if I have to use its mic, but would be nice to reuse the OEM one - I agree.
The OEM deck has about 5 connectors. After the obvious AM/FM antenna lead and the large power connector, I believe the others are probably for the Sirius, Bluetooth Module and the signal wires to the amp.
The problem is on the T-Harness, the picture only shows two connectors. The large one (with the "T" for connecting the OEM deck branching off it) then another set. I don't know what the other set is for but assumed it was the connector that led to the RCA leads.
I suppose we'll know soon enough, but I'm a little discouraged from Metra's site as well as that of the manufacturer (Axxess) that it doesn't mention any of those wires nor shows a wiring or connectivity diagram.
So, I'm expecting that stuff not to be there, but hoping they are.
I'd REALLY like to use the Sirius installation that's arleady in the car and take advantage of the built in antenna on the roof more than anything. I would hate to have to run that ugly magnetic one up there and sit it next to the built in one. My only hope is that because the Sirius module is relatively standard that if I can find it I might be able to tap into the antenna lead with another connector or something. My kenwood has the XM add-on, but they're pretty much the same anymore since they joined companies ( I believe Kenwood will support both XM and Sirius add-on modules anyway).
Well, I know from mine and zThrizzle's experience, the Connects2 Harness from the UK works on the 2011 and 2012 to let the A/C keep working as well as allow control of Fader, Clock, and Trip Computer from the steering wheel controls.
On all of the different sites where you order the Connects2 Harness from, they all say it is for CX-9 from 2009 and up. So I would take that to mean it would allow you to do the same on your 2010.
Here's the site I bought mine from. http://www.incarmusic.co.uk/category/1867/Mazda-CX9
I don't know where zThrizzle got his but it's the same.
I can tell you that the one unit that is supposed to "restore the parking tone" provides a Reverse and Speed Sensor wire whereas the other one doesn't. However, the Reverse wire did not work with my Kenwood deck so we still haven't found a way to get that to work.
If I were you, regardless, I would not try to retrofit the OEM nav. I've heard it is awful and you will not be happy with the navigation. I've not used it myself, but I've heard even from the dealership themselves that it is garbage and you're better off sticking a NUVI on your windshield.
Aftermarket units with NAV are much cheaper as well. The Kenwoods use Garmin's navigation so for those familiar with the Garmin units, they'll feel right at home.
