It's been 3 years since I bought my 945 and I was anxiously waiting for the 955. Well, it's finally been released and after reading DCRainmaker's review and comparing the features of the 955 and 945 on Garmin's website, I think I'm going to wait. The multi-frequency positioning system is the only thing I may be interested in because I've really had no GPS problems with my 945. The software features are just more add-on goodies I really don't need. I have no interest in solar or the new Elevate 4 HR sensor as I use a chest strap on all my workouts anyway. Speaking of chest straps, the website shows the HRM-Pro, Swim and Tri compatible with storing data on the 945 and just list the Pro and Swim with the 955. Is it an oversight, or would I have to replace my trusted Tri? Anyway, just curious on your thoughts?
