The 1.85 update is very insignificant for most of the US. There are only a few highways that use Speedinfo and if you rather pay $500 for a new unit that only has that in it, you're more than welcome to pass up on this deal. If those highways are not near you, this is still a great deal for its actual purpose. In addition, by turning TFM feature on for Speedinfo highways, you disable K-band radar detection. It's a catch 22 which I'd prefer to not have and save $200.
