No other single piece of equipment will affect your enjoyment more than the in-dash cassette or CD "Head Unit", essentially the main control panel for your car stereo. The knobs and controls must be easy to use, and the displays easy to see. The tuner must be accurate as well as sensitive, and the built-in amplifier (on units so equipped) must deliver clean, pure sound at a reasonable volume level.

  When it comes to head units, no other dealer can match Mobile One's selection. There are many factors which enter into the selection process of a new head unit :

the mount of choice by most car manufactures - has a flush face which blends in well with the dashboard for a ore custom look.

Some manufactures have built in anti theft devices; in the event a radio is stolen and loses power, an access code is required to reactivate the unit rendering the radio useless to a thief. Other manufactures have a built in car alarm. When you remove the faceplate, you activate the alarm; if the doors are opened or the alarm is tripped, the speakers emit an ear-piercing high-pitched alarm tone that will quickly drive a thief away.

Head units come in an array of formats, Cassette, Single CD, MiniDisc, Multi-Disc, Din &Half and Double Din.
