* Some vehicle manufacturers use their
own pin assignment. Especially the
terminals A7 (ignition plus) and A4 (steady
plus) are often interchanged. The incorrect
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-
tions A4 and A7 should be interchanged.
