How do I install the unit with the DIN Front Mount?
- Slide the mounting sleeve off of the chassis, using the removal keys if necessary.
- Check the dashboard opening size by sliding the mounting sleeve into it, carefully cutting or filing as necessary until the sleeve easily slides into the opening. Do not force the sleeve into the opening.
