* Some vehicle manufacturers use their
own pin assignment. Especially the
terminals A7 (ignition plus) and A4 (steady

connection in this case leads to following
problem: the unit can not be turned on if
the ignition is o and all the saved settings
are lost as soon as the unit will be turned
o. If these problems appear the connec-
