hi to all i recently remove old igo primo version and install new iGO Primo 8.5.9.142948 however all maps are there and etc, but i cant lock any satellite, any advice on this

Did you copy the old applications port and baud settings into the new applications sys.txt?

nope i didnt know about this and i deleted old one. however i kept the copy and here it is
[device]
type="prestigio 4050"


[gps]
port = 7
baud = 38400
set_messages=0
send_init=0
sent_init_type=0

this should work no matter for version

Then open up the new applications sys.txt and either add or edit as necessary...

[gps]
port = 7
baud = 38400

i fixed, just deleted device name
