@costas3850: I finally got the DIMKA skin installed. Now if I use the fixed station tmc, I can receive some info, but it seems very instable. It switches between "tmc available" and "no tmc signal" and "no tmc hardware found" all the time. And when I click on a specific tmc message, Primo crashes and restarts...

If I remove the fixed station ux, I do not get any tmc at all...

With igo8 on my mio, I could switch the device off while igo8 was still running and then switch it on again, and igo8 resume where it was left without any problem. I found this of course very handy. But with igo8, I did not use a sd card, so I thought that might be the issue.

@saviano: I do not understand your question? I used the visualgps unlock method and I removed most of the mio software.

Do you have tmc working with primo on a mio spirit 575? If yes, please tell me what you did!
