DIN Front Mount
1.Slide the mounting sleeve off of the chassis if it has not already been removed. If it
is locked into position, use the removal
keys (supplied) to disengage it. The
removal keys are depicted in “Removing
the Unit” on page 3.
2.Check the dashboard opening size by
sliding the mounting sleeve into it. If the
opening is not large enough, carefully cut
or file as necessary until the sleeve easily
slides into the opening. Do not force the
sleeve into the opening or cause it to bend
or bow. Check that there will be sufficient
space behind the dashboard for the radio chassis.
3.Locate the series of bend tabs along the top, bottom and sides of the mounting sleeve.
With the sleeve fully inserted into the dashboard opening, bend as many of the tabs
outward as necessary to firmly secure the sleeve to the dashboard.
4.Place the radio in front of the dashboard opening so the wiring can be brought through the
mounting sleeve.
