Yesterday after delivering my (fairly expensive) dog chow in Omaha I went by the company yard to have our shop look over my QualCOMM unit. After discussing my issues briefly with the guy who does many of the installs he had me open up my passenger door and took a look at some of the boxes of circuitry behind the seat. A light that should have been green was instead blinking red, indicating a problem with the antenna or the cellular modem.
After a few hours of waiting he was able to take a look at it and replace whatever wasn’t happy and even changed around the electrical system so I can turn on the unit by turning my key to Accessories! This has bedeviled me since the beginning with this new unit, as it turns off quickly after I shut my rig down and doesn’t seem to realize there is plenty of power coming from the APU. Now I can turn it on (and not interfere with the APU, as was the case before) whenever I need it while my truck is off.
If they fix the issue with messages being missed when the unit is off I think I will be in nirvana.
