I finally figured how to get TomTom 5 on Navman PiN 570, so here goes
Firstly turn on your GPS by going into "Start:Settings:GPS on SystemTab:ON"
The amber light should be flashing in the top left of your PIN 570
Next start tomtom
On "Main menu 1 of 3" tap "Change preferences"
On "Preferences 4 of 6" tap "Show GPS Status"
Tap "Configure"
Choose "Other Cable NME GPS"
Set "GPS baud rate to either 9600(worked for me) or 4800"
Now the tricky bit, this is where i got lost before
You are now faced with
GPS is connected to
SC2410 USB Cable:
COM3:
S2410 IRDA2410
S2410 UART0
GPS ON NAVIGATOR
Choose "GPS ON NAVIGATOR"
Done
Make sure your NAVMAN aeriel can see the sky and you'll be picking up satellites in no time.
Hope this helps took me a while to figure out but it definately works!!
