I just downloaded the new Palm Treo 650 update tonight. Worked great. The update just came out I believe yesterday. It's version 1.17. Its on the Palm website. The only thing I noticed that I had to pair with the Prius again, but now I get the working signal on the MFD. I see the bars move up or down just like it should. I have not noticed anything else yet, but I thought I just tell you guys about the update.
I believe he's refering to the Cingular version of the Treo. The Sprint update for this has been out for a little while, and I don't think there's been a Verizon update yet.
