I'm getting a feeling these "scanner" companies don't have good software release testing processes. It seems recently there are so many models from one company it is impossible to determine which model best covers your vehicle. IMHO it is all in the software... just what screen size do you want or need. My obdlink+ is still working - I'll remind myself not to update until I hear they have the issue fixed. Maybe I'll get my K7 working in the mean time.I typically give good ratings to my obdlink mx+. However, a recent firmware update has ruined it. I can use it to connect to cars through outdated Torque app. But using the OBDLink app crashes my phone. They are aware and are working on a fix. But come on, did they not try a beta version of the update and see that it is an IMMEDIATE crash of all hardware?
okay... I've done some testing of the KB K7 and I'm sort of not liking it too much. The software is too flakey. For one - when it was reading the VIN the dash display beeped and showed "Stability Sys. Disabled". Didn't give me a feeling. Easy enough to fix by cycling the key but still. Also a number of other glitches that are too much to describe. I'm going to give it a few more tries. The Innova might be a better choice.
Unfortunately I have an iPhone.If you're using an Android for the app, get "Torque" (Ian Hawkins) from Google Play. That version is free. Try it out and, if it works okay with your K7, buy the $5 Torque Pro version and get the GM Extended PIDs for it.
