My short commute home last night was interesting.....
For the whole ride, my ONSTAR kept breaking in saying,
"ONSTAR ready.....good bye.....ONSTAR ready good bye......"
And of course the readout on the radio would say "PHONE".
WHat the heck was that ?? And then for some reason the
readout on my temperature was all of a sudden in centigrade
not farenheit.
How do I switch that back ??

My truck is possessed

Thanks,
