control the vehicle.
Before final installation, temporarily
connect the wiring according to the
diagram near the end of this manual,
check it to ensure that it has been
connected properly, and test the unit
to make sure it is working correctly.
Use only the installation parts and
hardware provided with the unit to
ensure proper installation. Usingother
parts can cause malfunction and
possible damageto your CD
receiver.
If installation requires drilling holes or
othermodifications to the vehicle,
consult with your nearest dealer or
professional car audio installer.
Do not install this unit at an angle in
excess of 30º from horizontal, as it
may affect performance.
Avoid installing the unit in a location
which is subject to high temperatures,
direct sunlight, hot air from such
sources as heaters or exhaust lines,
or where it will be subject to contact
with dust, dirt, moisture or excessive
vibration.
For details about installing the head
