Unlock Sony NAV-u U93TC help please

[alex2_ar]

Hello everybody. I have a problem that i haven't been able to resolve by myself. I have a sony U93TC and wanted to put IGO8 on it. I have tried all of the sollutions posted here on the forum and the program launches perfectly but the GPS has no signal. The igo founds the gps receiver on port 5 and baud 57600 but still no signal.
The sys file is:
[interface]
resolution_dir="480_272"
vga=0
shutdown_time=0

[rawdisplay]
class="landscape"
screen_x=480
screen_y=272

[debug]
skip_eula=1
enable_roadshadow=1

[map]
auto_nightmode=0

[msnd]
msnd.start=0

[tts]
always_say_road_names=1
announce_street_name=1

[sound]
queue_length=200
ding=0

[gps]
port="5"
baud="57600"


and the navu mscr is:

RegWriteDword ("HKCU", "ControlPanel\Volume", "Mute", 5)

Kill ("SonyCalibMan.exe")

Close("SonyAppMan")

Copy("\Mounted Volume\Sony\nav-u\MortScript.exe","\Windows\MortScript.exe")
Copy("\Mounted Volume\Sony\nav-u\toolhelp.dll","\Windows\toolhelp.dll")
Copy("\Mounted Volume\Sony\nav-u\TestMode.exe","\Windows\TestMode.exe")
Copy("\Mounted Volume\Sony\nav-u\PowerOn.mscr","\Windows\PowerOn.mscr")

RunOnPowerOn ("\Windows\MortScript.exe","\Windows\PowerOn.mscr" )

RunWait("\Mounted Volume\Sony\nav-u\ToolDevice.exe","off 18")
RunWait("\Mounted Volume\Sony\nav-u\ToolDevice.exe","off 15")
RunWait("\Mounted Volume\Sony\nav-u\ToolDevice.exe","on Serial")

Run ("\Windows\TestMode.exe")
Sleep (50)
Kill ("TestMode.exe")

While (TRUE)
RunWait ("\Mounted Volume\iGO8\iGO8.exe")
PowerOff
EndWhile

I don't know what to do any more.
P.S. i have some background in installing other software on gps devices but this is beyond my reach. i have spent 3 days and still didn't find a sollution that works

Any help is much apreciated

It's really strange, that receiver is found, but the gps signal cannot be locked. Did you see any satellites on the display while iGO is searching? As I can see, the script is correct as it should work on most of Sony NV models..

I'm thinking.. maybe wrong baud rate could be the reason...You should try to delete this lines from the sys:

[gps]
port="5"
baud="57600"

and than use auto detect option in iGO8 settings. If iGO founds different values, than this cold solve the problem.
