enable igo primo maps on android from 8gig ram

Next day, the system time was one hour late again (the time zone is set), and I corrected it. I set it before clicking the GPS Info icon. One more thing I noticed that morning is that system time is one hour late. I started Primo and it showed 'Looking for satellites' and worked like a charm. When I clicked that it set the UTC time to accurate system time and showed some satellites. There is also a refresh-like button that asks 'Are you sure to reset GPS satellite receiver' when clicked. When that icon is clicked it shows the following info: Now, when I turn on the device, in it's menu there is a GPS Info icon. The sys.txt file is still there with all the needed info. I switch it off and on again, and it's still the same.

Next morning, I turn on the device and Primo says 'Autodetecting GPS receiver' again. I put the device to sleep and went to bed myself. It found a GPS fix very quickly and everything was fine. I started Primo and it finally said 'Looking for satellites'. After many attempts, I found the combination for this device on internet (port 1 and baud 4800) and put that into the sys.txt file. I then made a GPS port and baud entry in the sys.txt file and experimented with different combinations. I tried to use it like that, but it would just say 'Autodetecting GPS receiver'. The downloaded Primo had an sys.txt file with no GPS info in it. I then downloaded iGo Primo (because I wanted to have Primo) and loaded it on the SD card. I checked the SD card and found no sys.txt file on it. Upon switching it on, I set time and started Amigo, but the only thing it showed was 'Autodetecting GPS receiver'. The device came with an iGo Amigo loaded on SD card. I have found out that the device manufacturer is YF International and the model number is SKU 39243. I came here to seek help with a Chinese GPS unit I bought on eBay: Hello dear friends, this is my first post here and I am glad to be a part of this very promising community!
