I bought one of these as an upgrade to my Ipaq 3970. Although it's good in some respects it lacks in others, most notably sound volume out of it's internal speaker. It is about 30% volume of what the older Ipaq's can achieve. This is a major let down as I use it for mobile GPS and the voice commands are next to inaudible now. Was told you can buy small FM transmitter that will send to car radio that helps with this problem (even though I'm loathed to add wires to a wireless solution) Has anyone tried these and know if they are any good ?
