If you are having trouble with your blue tooth function you can always have it tested out using a bluetooth tester avaiable at this web site:http://www.ctscorp-usa.com/ Mine was giving me all sorts of problems and then I had it tested out using a blue tooth tester and I was able to pinpoint the exact problem that I was having. If you are having trouble with your PDA I strongly recomend you test it out first before returning it to the store
