The MEX-BT2500 uses the Drive-S chassis platform. Drive-S includes the CD
mechanism, audio stages, 12 V power supply, and tuner section. The CD mechanism
includes a suspension to resist shocks, a motor that draws less power, and a
fast low-current pickup that improves durability and CD playback accuracy. The
52W x 4 S-MOSFET Power IC produces clear, accurate sound, with little
distortion, and a high signal-to-noise ratio.
Front Panel Aux Input: You can
listen to a portable audio device by plugging it into the front panel 3.5mm
minijack auxiliary input. Note: The Auxiliary Input needs to activated in
the menu as a source before it can be selected.
This unit can play MP3 and WMA files recorded on CD-R and CD-RW discs in ISO9660
Level 1/Level 2, Joliet, and Romeo formats. Each disc should have a maximum of
150 folders and 300 files/folders. During playback, the unit displays any
recorded ID3 or WMA tag information.
Best Tuning Memory (BTM):
This feature selects stations with the strongest signals within the selected
band and stores them in order of their frequency.
EQ Lite: You may select one of
six EQ presets; Xplod, Natural, Hard, Upbeat, Vocal, or Custom. Each preset
(except Custom) has a preset value for bass and treble. For the Custom preset, you can adjust
the low (100Hz) and high (10kHz) bands from +10 dB to
-10 dB in 1 dB increments.
Loudness: When the Loudness
function is activated, the receiver gives a +9dB boost at 100Hz and a +5dB boost
Remote Control: The MEX-BT2500
comes with the RM-X304 wireless remote commander. Dimensions: Width=1.667",
For flexibility of installation, this unit can be mounted between 0 (horizontal)
and 45 degrees.
Illumination/Clock Display: Pressing the Off button once will turn off audio output, but the clock display
and face/button illumination remain on. This makes the clock display and
face/button illumination "Keyed" instead of "Unit On" only. To turn the unit off
completely, you must press the Off button for two seconds. When power is removed
from the switched power wire (the key is turned off), the display does turn off.
Note: When installing
in a vehicle without an accessory power wire at the radio location, you
must turn the radio completely off (this defeats keyed operation), or
you may wire the accessory power wire of this radio to an alternate
source of accessory power to retain keyed clock and face/button

Bluetooth Wireless Communication:
The MEX-BT2500 has
built-in Bluetooth hardware to integrate with Bluetooth
enabled cellular phones and audio players, including the Apple iPhone. Bluetooth (Standard Bluetooth version

listen to a Bluetooth audio device.
Up to eight phones or audio devices can be registered with the MEX-BT2500. Bluetooth wireless technology operates

and you hear the caller's voice through the front speakers (left, right, or
both). The microphone is built into the front of the radio.
