Finally find out how the car mode is triggerd
short circuit the ID Pin of the micro usb conector to any other pin will make my phone into Car mode and the car panel will popup if installed.
The ID-Pin is the 4th pin of the conector wich is the 2nd from left when desire facing up. Since the pc end of a data cable doesn't have the ID-pin, it won't work like this thread said

can someone confirm that

So this means that an amended cable would do it every time?

i think the menu is hidden by htc as the desire does not have the copper pins at the bottom like the nexus 1. hence the nexus 1 car dock wont work on the desire. the nexus one can be charged with the pins and does not need the micro usb for car dock chargings / docking. i guess the car dock software options shown on the desire by accessing the settings widgets are a hangover from the similar software on the nexus 1 hence hidden on the desire by htc.

i have the car dock app installed (dont remember from where though) and it works fine instead with navigation / voice search icons etc.

HTC is coming out with their own car dock. That is why their 2.2 ROM has the necessary support for it.

something like that has been on th expansys and other websites since april / may onwards! so i wouldnt take that too seriously till it actually arrives and car dock works when docking.

at present i use the car dock app which has to be triggered manually but works fine. i use it with the car mode app.

Yesterday i was driving with the car charger inserted in the Desire, when i was moving the cable sometimes the Desire gave a little car icon and my NavApp was activated. Sow i think i has something to do with the 4th pin, and you don't need a certan resistor attatch to it to get it in a certain mode.
