Deleting Directions in the Turn by Turn

I have 2 directions stored in my Virtual Advisor that were used as part of the turn by turn navigation feature of Onstar. One direction I sent to the car from Mapquest, the other I had Onstar download to the car. I don't need them now and I haven't been able to delete them. I called Onstar and what the representative told me to do didn't work. I can go pull out the manual but thought I might post and see if someone can just tell me simply how to do this.

I bought my 2010 LT1 in Mocha Steel/Ebony Jan 28. It has just turned 4,500 miles and everything is good except I'm still getting used to the transmission and the way it shifts. I said something to the dealer when I did the test drive and they said they would check it for an update, which they did. They said they reflashed the transmission. I thought I could tell an improvement at first, but now I'm not so sure. Is this something that might need to be done again or is it something to just live with?

BTW, I came out of a first generation Buick Lacrosse which was a major disappointment in my opinion. I chose the Malibu over the new Lacrosse simply because I'm going to put a lot of miles on the car and it is going to be sitting in a crowded parking lot where it will probably get it share of dings and all. I didn't see putting the extra money in the Lacrosse. In fact, I just like the look of the Malibu, I always have, from the first time I saw it back as an 08 model.

The one major wish I had for this car was to have a real tilt steering wheel. I am a tilt wheel user from way back. My dad had a 66 Chrysler with tilt and telescope and he and mother used to have to adjust it for their preference all the time. I guess growing up with that made me a tilt wheel user. Why I didn't catch this in the test drive, I don't know.

Additionally, I feel the LT1 was a good value. The little extra between it and the LS was well worth it. However, I don't quite understand the greater price spread between the LT1 and LT2. And while I really would have liked to have had an LTZ, I didn't see where it was worth all the extra they are charging for. And I would like to see the V6 option available on all models, not just the LT2 and the LTZ. My opinion, of course.
