2010 GMC Terrain: iPhone iPod iOS4 Fail Fix
September 14, 2010
About four weeks ago I complained about my iPhone 3GS and its sudden unwillingness to talk to our 2010 GMC Terrain. Other vehicles in our long-term fleet were similarly affected.
Specifically, the iPod side of the device was no longer recognized, to varying degrees, by most, if not all, of our long-term test cars with dedicated iPod connections. Overnight, all of the Terrain's clever iPod interface controls and display functions that had been painstakingly developed by GM engineers were worthless.
This sudden reversal of fortune sprang up after I "updated" my iPod 3GS to the all-new and much-ballyhooed iOS4 iPhone operating system. I was not pleased. Minor updates 4.0.1 and 4.0.2 were no help. I seriously considered downgrading back to iOS3.
Then, about a week ago, Apple introduced yet another update, a more significant step called version 4.1. If you can't "see" this update when you sync to iTunes and check for updates, you might have to upgrade iTunes itself to its own latest iteration, version 10. Do the iTunes 10 upgrade first, then you can get iOS4.1 -- got it? It's less of a hassle than it sounds.
I don't know if OS4.1 was aimed specifically at the automobile incompatibility issue or not, but it's entirely possible because my rant was far from the only one. Apple took heat from many others. No matter. Whatever they changed, and for whatever reason, it worked. It's all better here in the 2010 GMC Terrain.
Well, mostly better. I'm still not certain if every single iPhone-iPod function works, and I haven't tried it in too many of the other cars in the fleet. But this is a good start.
