COMAND retrofit with Harman Kardon Logic 7 Amp
There has been a great deal of forum discussion on COMAND retrofits but nothing with a full HK logic 7 retro as well.
Well--just completed a complete retrofit of a 2009 512 option COMAND with 810 option HK logic 7 amp into a 2010 C class with audio 20. Retrofit also included a UCI retrofit. The system is fantastic! So it is possible to for all that might be wondering.
This retrofit is not for the faint of heart. It required basically removing the entire interior to route the MOST cables and restring speaker cables from their original front to the HU to the amp in the trunk. Very hard taking 4 full days and lots of patience.
I'll post all parts used in a later post. Bottom line it is best to get as much of the equipment for one donor vehicle. That and thanks to comand online UK for retrofit kit.
World is difference in sound and this before even replacing the stock speakers. Even my dubstep loving son was impressed by the lows this system will hit now.
Having the large 7 inch screen is rewarding--no more squinting...
So if you have time, patience and money this is a retrofit well worth the contorted positions you will be in installing this system.
Altogether this project probably cost around $1900 after the buying and selling of parts settles. Outright I probably spent closer to $2800 outright but was able to offset some of the costs. The final product is better than I anticipated.
This weekend I had to Dynamat the rear deck due to the vibration from the subwoofer. $39 fix.
A total retrofit that includes the HK amp and surround sound is so worth the work. This is a complex project so not to be taken on if you don't understand wiring diagrams and basic electronics. If you do try this I highly recommend you do a ton of research and harvest as many of the parts as you can from a single vehicle. It will save you a great deal of aggravation.
So.... If you do not have an amp or sat radio then it becomes much easier. If you have only the sat radio then there is some rerouting of the outgoing fiber to the UCI instead of the HU and one final fiber line from the UCI back to the HU. You will then need the power cable and the cable to attach your iPhone to the UCI (this one is expensive). For directions on the retrofit I believe command online uk or mercupgrade has them on their site.
Let me know what set up you have and I can look up the parts you need to do the install.
Sorry for lengthy message but just not a simple answer.

My question is.... What should it be set too? Im starting to think there is likely a built in amp in the Comand head unit as well as the one in the rear which possibly just drives the subwoofer?
Any ideas?
