I think you are correct.
After doing a bit of casual research, I found that these units are sold under various names (Targa, Traveller, etc) at various discount general retailers such as Lidl, etc for very little money. The software that comes with them is a lowball version of Sygic Navigator X (unsure of the exact version, but it may be "5" or so).
Judging by what others have posted elsewhere, though the units are not actually 'locked', getting other software to run on them is a bit of a nightmare or impossible. Some seem to have gotten a more up to date version of Sygic to run, but, even though the maps are based on Navteq, nobody seems to have either updated just the maps themselves OR gotten iGo/Primo/ or any other major nav software to run. So my guess is that the version of WinCE has been highly modified to the point of being proprietary to the device and the software that came with it. Hence the low retail price of the units. Sadly, it may be a case of "You get what you pay for".
