XMPC-CAR for XM modified to fit 640x480 touchscreen...
I'm know I'm late getting to the XM-PCR party but I just bought one off eBay and installed it on my car computer about a month ago. I then found gork's wonderful app. Thanks to gork's generosity I was able to compile a modified version of his XMPC-Car Tuner to fit my 640x480 touchscreen. The problem was that the signal meters scrolled off the screen so I played around with the formatting in the source code until it fit my touchscreen. Below is a link to my modified .exe and a screenshot. BTW, I use a dark desktop theme on my car computer so the screen won't blind me at night. Also the red and blue font colors blend in perfectly with my Jetta's dash lighting scheme.
