[Hi I have had the same problem with "simulated input" comment, i had tomtom6 and MemoryMap on the same card, the only way i can get it to work is have seperate cards for each program.
The Mio P350 is set to
GPS program port COM 4
GPS hardware port COM 2
Baud rate 4800
The TomTom6 is set to
Other NMEA GPS receiver
Baud rate 4800
GPS connected to GPS_COM
MemoryMap is set to
NMEA
Port COM 2
Baud rate 4800
I hope this helps, if anyone else can suggest different settings that work for them, please let me know
