iGO cannot find gps receiver // HELP~! //

[yjjadara]

Hi, there,,,

I am really frustrated because my TP2 iGo cannot find (internal) gps receiver.

I followed the guide of iGO 8.3.4.102680 with proper data.zip and branding. zip.

Everything(routing, searching maps, poi) is working fine except gps signal.
I tried autodetect, then it says " gps receiver cannot be found".

I spent two days to solve this problem, but no luck until now.
Please Help me...

What I tried..
- removed WM marketplace, (someone said it is conflicted with iGo gps.)
- go gps setting -> set port 4.
- in sys.txt [gps] port = 4, baud = 4800 or 9600 or whatever.
- etc.

My Pro2 is working with Google maps, or Bing navigator.
But I don't know why iGo cannot find GPS receiver.

Autodetect sometimes tries to turn on the Bluetooth.
But I cannot find any setting of bluetooth within iGo.

I appreciate if someone help me to get gps signal withing iGo 8.3.4.
I cannot do other things before solving this problem.. T.T

Thank you,

p.s. I put my sys.txt.
