A client from Chesterfield contacted Extreme Audio to inquire about replacing his 2007 Mercedes-Benz CLK350 radio with a navigation system. We inspected the clients’ car to confirm our understanding that it uses the MOST fiber optic system to connect the factory head unit to the factory amp. Once we knew this for sure, we designed a replacement system using Alpine products to give him the features and technologies he wants. Let’s look at the work we performed…
Alpine Navigation System
We started the project by removing the factory Comand radio from the dash. The upgrade plan was focused on an Alpine INE-W960HDMI source unit. We connected Stinger 6000-Series interconnects to the radio and integrated the power and control wiring into the factory harnesses. We used a PAC Audio SWI-CP2 interface to connect the factory steering wheel controls to the new radio. The dash kit for the new radio is an NTV-KIT742 from NAV-TV.
The Alpine unit includes a 6.1-inch touchscreen display, built-in navigation, Bluetooth and an SXV300 SiriusXM satellite radio tuner with three months of free service. The system will play MP3, WMA and AAC files from a CD-R, DVD-R or a memory stick. The client can also connect an iPhone or iPod to enjoy his iTunes collection and charge the battery.
Because the factory amp uses a MOST fiber-optic connection, we chose to replace it with a pair of Alpine KPT-455U amplifiers. Interfaces are available to allow an aftermarket head unit to work with MOST amplifiers, but given the vintage of the vehicle, investing in new amps made more sense. One amp powers the front and rear speakers in the doors. The other amp powers the speakers on the rear parcel shelf and the factory subwoofer.
We mounted the amps to the factory amp bracket on the right side of the trunk. We bundled all the wiring with automotive grade cloth tape to give it an OEM look.
Mercedes-Benz CLK350 Radio Replacement
With the CLK350 radio replaced and the amplifiers installed and configured, it was time to turn the car back over to the client. He was impressed with our clean installation and was thrilled to have navigation for his frequent trips to D.C. We showed the client how to pair his phone with the radio and reviewed how to change sources and enter navigation directions.
