Mercedes and other German automakers have always been trickier to install aftermarket head units in due to space restrictions, CANBUS/Data related complications, and a host of other integrated systems tied into the factory receiver. That being said, companies like Axxess and Connects2 have products that are specifically designed to allow for radio replacement in these vehicles. We were able to retain the advanced fiber optic amplifier system in this car as well as the steering wheel controls with parts from Axxess.
While these modules can be quite expensive as they need to communicate with the factory amplifier, steering wheel controls, and retain NAV outputs (such as reverse trigger and vehicle speed sensor), they can still often be cheaper than replacing the head unit with factory components.
A quick search of even used Mercedes COMAND head units with navigation and their relevant map updates can easily put us over $1000 in parts alone. Not only that but the tech designed over a decade ago just doesn't compare to even entry level head units today. The Kenwood DMX7705S double din receiver we installed in this Mercedes has awesome features such as:
- 7" LCD Touchscreen
- Android Auto and Apple CarPlay (through USB, 2x Ports)
- HD Radio
- Kenwood WebLink
- Dual Camera Inputs + 1 RCA Video Out
When paired with the backup camera, the car feels modern again with excellent connectivity and convenience features that may not be found even on the newest Mercedes vehicles. Furthermore, the 6-channel RCA Pre-outs found on this receiver are great for future audio upgrades like speakers, subwoofers, and amplifiers that can easily make this older E-Class surpass the sound quality found even in the highest end Mercedes models!
