Market Research

Gosh, I've been looking for the answer to a simple question, and after a few hours, I still can't find the answer! I just want to know: Who are the #2 and #3 players in the GPS Asian market. Google has tons of information on Europe and USA, but nothing on Asia! (well, there are some, but we gotta pay like $2000 USD for each article). If I become a marketing professional in the future, how in the world am I going to do market research without spending a fortune?
