Thread: What can cause dropping satellites after 20-30 min. drive?

There is no special version for Trucks @ iGO. That is quite normal, standard version, but with adjusted sys.txt, and/or some truck dedicated skin, and/or modded data.zip or added branding, and with truck related content (extra Truck POI's, FTR files).
But, not every iGO version is suitable for every device. Some versions behave better with one type of device, some with other...etc. So, if your device is fully functional, then you stay just to try more of them.
Good thing with Primo same version (2.0 in your case), is that you can change only main exe and everything will work OK. You can also replace data.zip with that goes along with that version.

However, the problem that appeared to you, looks to me more like a problem with the device itself.
You've only got to try all the possibilities.
