There was another bugfix in last FW. In Germany where you can drive fast at German autobahn, the older FW was showing an speed limiter of 155km/h at unlimited tracks. This is now fixed. The 155km/h sign will not be shown anymore.
I and some other german users of the 5.16“ display are searching for a download of „Tsl32_V3..0230407,1,4“ too. Hansshow seems to deliver newer FW with fresh ordered displays but forget to update the download of this FW at the own home page.
