I brought this up to my dealer last week when my ES was in for service. He said there was a TSB out but I would have to leave the car because it will take a couple of hours. I couldn't believe this so I found the Toyota Tech Support site and for $15 for 48 hour access I went looking for myself. I found 2 TSBs, L-SB-0039-09 and TSB2646, that cover the IPOD problem plus other problems. I had the TSB, L-SB-0039-09 done today. IT SOLVED THE SCROLLING AND AUTO-START PROBLEM. This was the 1st time they had done the TSB and were a little intimidated on the 13 pages.
I called about 1300 EDT and they were just starting on it. By the time I went out and got lunch to bring home to eat, about 15 minutes, my service writer called me to say they were done.
I think there were 2 problems with my dealer doing the TSB, 1. They had never had to do 1 like it before, and 2. It wasn't really affecting the operation of the basic vehicle so they didn't see they need.
I also asked about updating the map data and was told they would have to order the parts and it would cost close to $500 to update. I said no thanks.
Bottom line is that the TSB, L-SB-0039-09, fixed the IPOD scrolling and auto-start problem. I am happy now.
Hope this helps.
