I have an HTC Wildfire S which keeps putting itself into Car Mode. I cant find anyway of stopping this. I have checked HTC website which tells me to go to settings , the car panel, and uncheck auto launch.
But there is no Car panel / Car settings. I have searched the phone and nothing related to car mode appears. Also the speaker phone automatically comes on when I make a call.
I have tried a software update but there is not enough space on my phone to install it , despite me having only 1 app I have downloaded.
can anyone help?

If it's like my desire HD then it's the slot where the USB cable plugs in. I blew mine out with some compressed air at work and haven't had a problem since.

EDIT. This is for the car mode problem.

How big is your phone now?
