how do you enable the 390 TPWS? I can not find a switch for this the twist switch to select normal or isolate does not seem to work am, I missing something? 390 is well modelled to be fair I have only driven the 390 on training centre training interdiction to 390, but if I was to drive on the WCML South route I would still need to be able to switch it on.
There is another switch in the right side of the top row of switches. You need to activate both of them.
