A—Mount the Cradle and Connect Your iPod nano
1. Gently slide your iPod nano into the iPod
nano cradle until its dock connector is firm-
ly seated;
if you are using a full size iPod or
an iPod mini, skip to the next section.
2. Decide on a mounting location in your
vehicle for the iPod nano cradle; make sure
you can plug in the iFreq into a car lighter
jack and that its cable won’t interfere with
safe operation of your vehicle. Note where
the magnet will be mounted.
3. Clean the surface that you will attach the
magnet to, remove the backing paper from
the magnet, and press it firmly; make sure
the surface is dry and clean before you apply
the magnet.
4. Snap the cradle on to the magnet.
