ok guys heres what im working with its a lea-4a made by u-blox
heres datasheet in pdf

http://www.investigacion.frc.utn.edu.ar/sensores/GPS/LEA-4x_Data_Sheet(GPS.G4-MS4-06143).pdf

heres intergration pdf

http://www.nalresearch.com/files/Tracking%20Modems/9601-DGS-LP/9601-DGS-LP%20SW%20Version%201.2.0/Manuals/GPS%20Technical%20Documents/4H/ANTARIS%204x%20Modules%20(GPS.G4-MS4-05007).pdf

ok what i need help with is in the integration manual sec 4.4.2 pg 81 figure 68 there is a schematic for usb but the capcitor and resistor values are not listed anywhere.
if any one could help that would be great.
i already have power and the antenna worked out its in a ignition interupt gps locator
dealers put in cars for recovery if non payment. but don't worry the trucks paid off.
thats how i got the idea for the gps.

also this is for a project im working on for my 98 expedition installing 19in touch screen with windows or linux machine running xbmc more than likely windows cause its drivers are easy to find. and this will let me add one more thing to it with gps.

and again thanks hope someone can help

i can't wait to get the parts ordered and get started on this project. i will keep those who are interested posted as i work on this. i will provided detailed parts list and instructions the best i can. keep in mind im new to a lot of this. im great with simple stuff but as long as i can get to the info i will give it a shot.
