That 198 is due for an upgrade....! I saw you in Pulpit Sunday morning, I would have stopped by for a gam but I had a tight schedule.
I got a dealer e-mail the other day from Garmin announcing their newest GPS antenna the GA 38. This iteration includes Glonass compatability as well as the US GPS system. This is all part of Garmins interest in expansion into their other markets, aeronautic, auto. not to mention the fact that the Russian gov't has mandated that all devices have GLONASS built in.
"To improve development of the user segment, on August 11, 2010, Sergei Ivanov announced a plan to introduce a 25% import duty on all GPS-capable devices, including mobile phones, unless they are compatible with GLONASS. As well, the government is planning to force all car manufacturers in Russia to make cars with GLONASS starting from 2011. This will affect all car makers, including foreign brands like Ford and Toyota, which have car assembly facilities in Russia."
