Eystar has just introduced a bluetooth GPS receiver, making GPS available to anyone with a Bluetooth-enabled cellphone, PDA or laptop. The GPS receiver features a battery that holds a 15 hour charge and a 20-channel all-in-view tracking SiRF Star III GPS receiver. The EyStar Bluetooth GPS receiver will retail for $100 when released in early 2008. Microsoft Street and Trips navigation software is also required so keep that in mind.
