There is no room to drill the 3.5mm aux port hole on the face of the CDR-210. It is only available on the CR-210 since there is more space. AFAIK only Becker does it.

 

yes, sent it to here... http://www.beckerautosound.com/Service.html over in Jersey

 

Sorry for any confusion I may have caused
I have a CR 210 cassette player (Not CDR 210 CD player) and it does have a knock out in front that Becker will install the input in it's place

As Ilko mentioned, there is more space on the CR-210 and it has a knock out

 

Ah, ok got it. However, the CDR-210 does have the remote CD changer interface plug on the rear and that's what the aux adapter plugs into for sale on eBay that Ilko posted the link to ... is that right? If so, then when Becker provides a Bluetooth plug in, it should be able to just plug into the line out of the rear adapter thingy and work as well ... maybe just tuck it in behind the knee bolster under the dash and ... no wires :-)

 

Both the CR and CDR have the CD changer interface connector. Not quite sure how the bluetooth would work. Also I'm not sure how Becker made the Aux plug work. Looking at their newer PCM Aux solutions, they tap into the FM radio...

 

Yes, it must tap into FM radio... When I play iPod, FM station still displayed and artist currently playing on station is displayed

 

^^^ well, I'm no stereo or bluetooth expert by a long shot, but it seems if the adapter works as described, you would access it through the function button (S) on the far right of this picture .. not sure how the display would handle it, should show any metadata associated to the track i would think .. the bluetooth plug-in would just eliminate the hardwire to the phone/ipod .. should search and pair up and run any audio through the system ... am I crazy or just a moron?
