We decided not to replace OnStar communication module that died 1/2 thru our trip to TN. The TN GM dealer quoted the replacement and labor @ $550. Once @ home our local GM Dealer quoted us a replacement cost of $300 saying that GM out of good will would cover the cost over $300. If we need turn by turn directions, we will buy a GPS. The module should not have died in our opinion.
Update from Nov 19, 2014: Both GM dealers left the failed onStar module hooked up and that resulted in battery drainage. Shortly after returning home from TN to MN, we had to replace a 2 - 2 1/2 yr old battery; however, the MN GM dealer didn't consider why that battery was drained and we agreed to replace, at our cost, the battery w/new GM battery. One week later that battery was drained and car would not start. The onStar failed module had to be unhooked to stop draining the new battery.
