Question about sys file

Hello!

I'm new with iGo Primo before that i used only 8.3. Today i installed Primo onto 2gb sd card so far so good everything seems to work (no out of memory error). I use a Chinese 4,8" gps device.

Question: I checked my sys.txt file and i found only these lines:
[device]
type="navon_N750"

[gps]
Port=2
Baud=4800

usually the sys.txt file is full of lines, but my one is short. I wanted to know is it ok if i change my sys.txt file with these or at least take some lines that might be useful:
[debug]
cache=2048
reserve_memory=2000000
sound_q_length=200
tts_min_ready_wav= 1
tts_getaway_time=100
tts_expected_engine_delay=400

[gps]
Port=2
Baud=4800

[interface]
resolution_dir="320_240"
extra_settings=1
vga=0

[navigation]
sim_speed_factor=3.0

[power]
backlight_sync_with_OS=1
powermgm_state=0
backlight_day=100
backlight_night=54
skip_suspend_process=1
skip_resume_process=1
skip_suspend_process_all=1
skip_resume_process_all=1

[rawdisplay]
screen_x=320
screen_y=240
stretch=1

[sound]
ding=0
queue_length=200
mute_os_key=1
pause_mp3_sooner=1

[speedcam]
enable_at_startup=1

[tts]
automatic_direction_conversion=1
tts_buffer=131072
announce_exit_directions=1
tts_logics=3
priority="CRITICAL"
always_say_road_names=3
announce_street_name=1
skip_exit_numbers=0

[warning]
speedcam_enabled=1
speedcam_visualtype=1
speedcam_soundtype=2
speedcam_soundtype_4=2
speedcam_warning=1
speak_tts_only=1
speedwarn_alt_builtup_based=1
speedwarn_alt_limit=1
speedwarn_alt_tolerance=100
speedwarn_alt_toltype=1
speedwarn_tolerance=100
speedwarn_toltype=1


Thank you!

If it works as planned then i'd leave it as it is, Here's mine for reference...

One question pop up. I have speedcams intsalled. I made simulation test and when the arrow past the speedcam (the speedcam logo was on the map) but the GPS didn't made any warning signal or noise.

Do i have to add this line to my sys.txt:
[speedcam]
enable_at_startup=1

or this:

[warning]
speedcam_enabled=1
speedcam_warning=1

The speedcam warnings only work when you are actually going past a camera, Not in simulation mode.

You need an actual satellite lock. Not in flyover or simulation.
