Thanks for the feedback, it uses DirectX 8, one problem is my Car PC is an old Lenovo Idea Pad (Atom based with Intel graphics), it's very slow though I'll be upgrading it to a Core i3 system soon enough. I'm happy to share my code if you're interested in working from it - it's coded in a way that's easy to add new features without needing any knowledge of DirectX.
nice stuff man, i am a fan of the work! ive been writing my own stuff for years now, im on to my 3rd carputer vehicle, and am also a vb6 programmer. the screenshots make me think youre using directx for the graphics, something im just starting to learn. been with vb since 3.0 though. i recently sat down and figured out the serial communication between a hdradio addin box and its faceplate, so maybe i can help you figure out a radio solution. nice work, and im glad to see im not the only person that wont settle for whats out there and decides to create my own interface to suit my needs
