TCU is a completely different computer to the DME, so not affected by xHP flash.
Thanks Protecon for the info. I was thinking of MHD or *********** that work directly with the JB4. These options are not available for our S63.
Do you think that the xHP upgrade is worth it?
Did you disconnect the JB4 completely on installation or just load map 0?
