Seems I found a version that works. I also reformatted the replacement card with the SDformatter program and created the "save" folder before using. Don't know if those made a difference since I did them all at the same time. Can also use the map files that came with the head-unit by copying them to the map folder but turns out they are from 2013. Here is the link to the mfgr website:

From their description, it seems that the unit supports TMC through the use of RDS or somehow, yet the iGO software does not detect any stations. It did not work with the original program either.
I copied these lines from the sys.txt to the replacement sys.txt:

[tmc]
internal_tmc_name="gnsport"
source="gnsport"
port="COM,7"

If the radio says that it supports RDS do I need a separate antenna for that function?
