I'm not getting anything from my unit. It's not even putting up the reading boxes where the the speed and such would be. I checked my connection at the Unit and it looks OK and have put Dielectric grease in the connections. I've tried System Restore a couple times and checked the pins to see if any were bent and there weren't any. If I remember right, it didn't show water temp either for some reason. Could this have something to do with the new update in the software I just did? If so, can I erase the new update off the Sim card and put the old one back on it since I did save the BIN file. Any of you got any ideas on any of this?
