My 2010 Malibu just turned one year old, so my one year of free Onstar ended. I called Onstar and they wanted $300 + tax for the Directions and Connections plan. They were just about to bill my credit card and I told the representative "I heard that Onstar Offers discounts". I found that out from this forum. Sure enough, she checked into it and I got 1 year of Directions and Connections for $240 + Tax. Just a simple question and I ended up saving about $70 with tax.
It bothered me a little bit that I had to ask for the discount. Why didn't they offer it to me in the first place?
In my opinion, if you have Navigation, it's worth it to spend the extra money for Directions and Connections. That's the feature I use most with Onstar. All the other features are great, but you really don't use them much unless there's an emergency situation. I even use the Directions and Connections to get phone numbers and addresses. It's a lot cheaper than calling 411. And you can even get phone #'s and addresses from your home phone.
So if you're renewing, ask for the discount. You will probably get it.
