Didn't see this posted so I thought I'd post a tip about onstar navigation. I like looking up destinations on mapquest and then sending it to my onstar for later use, but I hated that it would only let me store 5 destinations.
Today while messing around while bored I found that I could store more destinations. While on a planned route hit the phone button and say "Store Route Destination". So today I went through my list of destinations I stored on mapquest and stored them using this method, then went online and added more destinations on mapquest.
When you need to the destinations just hit the phone button and say "Plan Route" then it'll ask you to say the name of your destination.
Anyway I hope it helps some people out there
