So ... as with many of my cars in the past, I've decided to opt to upgrade the OEM ford sony stereo in the S-Max
firstly, the car in question is a 2008 2.0 tdci titanium with the Sony 6000CD (not the Dab version) click here for image of unit
Having purchased the Stereo (a clarion double din navigation unit) and also the iso harness adapter from dynamic sounds, I find myself for the first time ever completely stumped.! I fitted the unit however could not get it to power up.. So on the stereo units wiring I connected the acc+ (red) to the same 12v feed as the standard 12v (yellow) in order to obtain a continuous supply..
So this works.. the memory works, the unit powers up etc.. although I have to now manually turn it off each time I stop the car engine as its not controlled via the ignition power. This I can live with, being just a minor issue, however the bigger issue is that since installing the unit, the car alarm goes off randomly at various times throughout the day/night.. I removed the unit and put the OEM one back in and now the alarm issue is resolved..!
the oem connection is the Quadlock.
Thanks in advance to anyone who has any knowledge of this issue
