I didn’t say it was a two-minute job. I said take your time...
The device is in front of your nose, you should have some manual too, right?

Each system has its own specification and menu in which it can be seen. The same goes for software - "about menu"...

Obviously, as soon as you confuse the distributor with the type of software, your knowledge is low. It is not my intention to offend, it is a fact and it is normal for beginners.

Most likely your system is based on the WinCE platform, and most likely uses Primo. Such devices do not connect to a computer, but contain a SD card containing software and maps (or just maps).
Even if it is Android based, routing is never necessary in cases like this...

First establish the facts about your device, and then look for the right information you need. When you find out, we can give you further guidance.
Everything already exists on this forum, there is no need for new questions, all you need is good will and enough time.
