Hi Everyone, new to the forum and new to Bimmer's. Two days ago I purchased an E53 2006 and one of the first things I am considering is changing the audio/nav system for an aftermarket version. So I have been reading though this thread and you would have thought from its title it would have put me off an Eonon or similar unit but strangely enough I am encouraged by the accounts in here, lol.

Anyhow I have a few questions some you gents no doubt will be able to assist me with.

The model E53 I have is the audio/navigation version and looks like it has no DSP - no subwoofer and no DSP in the main menu however it does has the BM54 amp located under the spare wheel. Question is do I need to run cables to the BM54 from the head unit when installing an aftermarket unit ?? If so what is the best cabling route to follow, straight up the middle or up the passenger side and crossover under the front seat or is there a better alternative?

Is the functionality of the BM54 amp re-used with installation of the aftermarket unit ? If so I think I have a problem because the drivers side door speakers don't work at all and I believe it must be a dead channel in the amp.

Lastly is there any recommendations for brand/models ? I know the thread is about Eonon but I have seen Xtrons, Dynavin and others mentioned. I can see on Aliexpress an Eonon 6166X model that comes with the 5m extension cable so is this the latest model? I also see various model of Xtrons available that don't come with a 5m cable. I can also see a Dynavin available in my home country ( NZ) but its nearly three times the cost of the units available from China and seems to be a lower hardware spec than either Eonon or Xtrons. So any advice or pointers in the right direction would be very much appreciated.

One more thing - did anyone have any luck in getting rid of the Eonon logo ?

regards Phil
