Took a look at the GoPhones for sale on the AT&T web site and found the ZTE Z667 Go Phone (
http://www.att.com/cellphones/zte/Z6...sku=sku7460773), usually $59.99 on sale right now for $49.99.
It operates on Android 4.4 (KitKat), which is the same operating system as the LG phone from Verizon that I mentioned previously, so it should connect to the Vette, including the Contact List, without any problems.
Sir Nuke: Are you sure that using the steps you suggest you aren't using the OnStar phone, which would require purchasing minutes from OnStar? Only reason I ask is that with my 2010 Camaro I could add contacts as you suggested, but was asked during the process if I was adding contacts for the OnStar phone or the paired phone. The prompts from OnStar would seem to me to indicate this setup was only for the OnStar phone.
