This tells me a lot, and the mistakes are solely yours. All of them.

- There is no adequate truck content for Luna (does not exist). Use PAL.
- As soon as you couldn't get Luna to work, it means you didn't follow the installation process. READ CAREFULLY, and follow the instructions exactly. Software in internal memory only. The content may be on the card. Browse the Forum, all instructions already exist.
- All links for TT Go and Sygic Truck are active. They are each in their own section. I can't browse and read for you.

Everyone has an opinion, and I told you that everything is used. Each of the bus drivers uses several of them in parallel almost always.
