First go
H E R E and read all, I suggest you do it slowly and twice so you understand. Download the program.
Unrar the downloaded file on PC, then you wil get a folder called igo. Open it and rename the file igo8.exe to Navi.exe.
Open the file called sys.txt in notepad. Search for
;resolution_dir="320_240" delete the
; then edit "320_240" to "480_234".
The sentence must now be : resolution_dir="480_234"
Close and save.
Rename the iGO folder to Navi.
Copy the folder to an sd card, put it in the device and start it. There should be a start navigation button somewhere, a hardware button or screen button, I don't know. Start the navigation program and do the initial settings. (language and voice). See that you have a clear view to the sky and wait for a gps fix.
Report back.
Remark : There are no maps and other content yet. We will see to that later. First get iGO up and running
