Hello, I would try not to use MDC to update go 600.
I know that I should use TTB and choose an official predownloaded Navcore (for example now I have gor 18 and would like install 22.100)
I have got alrady official navcore 22.100 but to use TTB I must connect my nav4 in normal mode or in recovery mode? Magic sd card? MDC opened?
I cannot understand the correct procedure..

And.. second question.. after updated navcore by TTB how can I delete official map in internal memory without MDC? After this I will install new map using TTinstallmini.
Thank you!
