Hobbyking OSD - GPS Sirf GPS2e LP-7451 chipset

Hi,I have just recovered an older GPS module from my Bixler prior to an APM2.5 upgrade. The GPS still works and locks so I am thinking - a spare GPS, why not?The GPS is based on a discrete Sirf GPS2e LP-7450 chipset, which I think defaults to 9600 baud NMEA. Availble pins are Vcc and Gnd (5v), TXA, RXA, TXB, RXB, and Boot. Reading a data sheet indicates that it can be changed to Sirf binary output. I am guessing it is TTL logic compatable.So the questions are: Is Sirf binary compatable with APM? I have heard of Sirfdemo, can I use it to setup the GPS? Or is there another way?It looks like the module was originally intended for a GPS mouse, since the PCB is round. The GPS is ex cheapo HK OSD, which doesn't OSD anymore.I am aware that this is relatively old tech but it seems a shame to waste it if it can be used.Grateful for any assistance.RegardsAlan
