I am having connecting issues connecting to an 03 H2. I had a similar problem connecting with my corvette the first time. I unplugged the cables, restarted the software (a couple of times in a couple of different orders) and got it to work, from that point on, it connected first try every time. I haven't had any luck getting connected to the H2, the same laptop, cables etc... won't finish connecting to the H2. I get a couple of different errors. One says something about an invalid calibration...connecty anyway??? The other gets a bit further along in the connection process, it gives the 1 sec retry a few times, then holds for a bit, then I get bootloader rejected.
Any ideas??
