I was looking on Amazon over the weekend for PC steering wheels when I remembered that my phone could do the job! Install JD SimWheel from the Play Store, grab the device driver and server from here for your PC and you’re 90% of the way there.
It might take a few minutes tinkering with the settings in-game but Euro Truck Simulator 2 works fine with it. I still can’t reverse properly but now I can take corners smoothly and two of the buttons on-screen are already configured for left and right indicators!
Here’s a howto video and demonstration using the game GRID created by user MyHD2AndOthers on Youtube.
Next on my todo list is using a WiiMote as a steering wheel as I already have the steering wheel adaptor for it and it should be more comfortable than holding a phone!
