Hi All, New to the Xoutpost after purchasing an 03 4.6is Estoril beast.
I've been reading lots of your helpful posts trying to fix a bunch of things: floppy mirrors, broken window regulators, broken sunroof etc etc.
I have however recently fitted the Avant 4 into my machine and have been trying to get some of the issues you speak of sorted also.
The install took me two days which included wiring for a front and rear camera as I had Nav. I've found that some of the features dont quite work as advertised also. I have contacted the ibus peeps and have a reply for some of the issues but not yet all. I found that setting the code oem feature messed up the outside temp. I also have an issue with consumption. I wanted km/l. the stereo shows this, the car does not. If I code oem then the stereo shows the corrected value. If I dont code it then it shows the value for l/100 but with the km/l units. Strange. I have the ibus unit hooked into the previously mentioned main loom situated directly behind the stereo. I have had zero issues with it talking to the car.
So far I have found this stereo to be pretty good. While it was an aZZ to fit it was much less work than what I have done on my E39 which is relocate the factory stereo into the boot to keep the obc going.
Looking forward to reading more useful posts and perhaps contributing more as well.
