AutoMapa on S100 Car system

Hi, I had iGO navigation on my S100 radio (based on WinCE).

It worked but it was too old (10), so i decided to install newest AutoMapa's maps. It works... almost, because there is no sound from AutoMapa. Car audio works. I put this sd card to other WinCE navigation system and it works there, but not in S100. I didn't put any sys.txt file on the sd card, but previous file for iGO looked like this:

[debug]

reserve_memory=1500000
cache=2048

[gps]
port=2
baud=9600

[tmc]
saved_config_available="1"
saved_config_classname="NMEA_GPSTMC_AMARYLLO"
saved_config_portname="COM"
saved_config_port="5"
auto_tuning="1"
port="COM,5"
baud="9600"
source="amaryllo"
enable_flow_events=1
flow_stripe_blinking_time=1000

Any suggestions?
