Not sure what the missing link is here. But JD got the titan radio to work on the touch. SO....in theory....with the drivers that Ethereal has, and the radio that JD ripped..can we get the GPS to work on the Touch??
The titan radio thread is here (sorry if the link doesn't work, search for 3.27 titan radio in the Touch Forum):
