Both I and my friend (who has a roadster) would like to use the newer/better cell modems. And the extra cost of the module that causes you guys to choose not to mass produce and sell isn't a barrier for us. If bare modem boards were available how hard would it be to populate some with newer cell modems? If everything has exposed pins I'm sure I could do it (I've built a few small boards of my own design and have a stereo microscope). But if there are any BGA involved I wouldn't want to attempt it. (Looking at the pictures on fasttech.com I don't think this is will be a problem.) And at some point I also want to use ovms in my J1850/Class 2 C6 Corvette. I'm very familiar with the J1850 side. But I don't know which approach would be best: either adding a custom board internally or making an external j1850 to can bridge (could it plug into the HUD port?) Craig
