6. The AM/FM antenna is located at the audio gateway (AGW). To interface with the
factory AM/FM antenna you must use an antenna adapter (Metra 40-EU10, not
provided) as well as an antenna extension harness (not provided) which must be run
from the AGW to the front of the vehicle and into the antenna input of the aftermarket
radio. The location of the AGW varies in each vehicle. The AGW in the SL is located
behind the driver’s seat in the side panel. On the E & CLS class it is in the driver’s side of
the trunk behind the carpet and sandwiched between the outer skin and trunk support.
On the S & CL class the AGW is located in the driver’s side trunk behind the carpet and
on the door. The AGW in the SLK is located in the front of the vehicle below the
passenger foot well.

FAQs
Q1: The OPTI-1 works fine on AM/FM but as soon as I put a CD or DVD in the unit all sound
goes away.
A1: Some aftermarket head units have an amplifier turn on wire as well as a power antenna
wire. Normally, an amplifier turn on wire is blue/white and a power antenna remote wire is
blue. The power antenna remote wire only outputs voltage when on Am or FM modes. The
solution is to connect the blue wire from the OPTI-1 to a wire that outputs 12 volts + in every
mode from the aftermarket head unit (blue/white)
Q2: I installed the unit and I have lost all bass response in the vehicle. All the speakers are
playing but I have no low end.
A2: Some aftermarket head units have cross-overs built into them that limit either low
frequency or high frequency response. Refer to the owners’ guide of the aftermarket head unit
and turn on any high or low pass electronic crossover in the head unit to ensure a full range
output.
Q3: I installed the unit and all I hear is bass but not high frequencies.
A3: Refer to answer 2. Also, make sure that you did not attach the RCA inputs of the OPTI-1 to
the subwoofer output from the aftermarket deck.
Q4: The OPTI-1 works and sounds great but I can only get balance left and right to function
and not front to back fade.
A4: The OPTI-1 does not support front to back fade due to the lack of any available aftermarket
head unit with a communication network. Balance will function but fade will not.
