I have a question about my Kenwood KDC-MP205 I need some Instructions to my model Please because I have one but my friend gave it to me as a gift lost the instructions to it.

Unless you turned it off, Kenwood radios automatically have the loud turned on when the radio is first powered up.

if there is no aux port on the front(if there is just plug it in and press source till it displays aux) it is in the rear you will need your deck keys to remove the stereo and most likely it is a rca to 3.5mini jack run this cable to your glove box

Page 28 Removing the Unit....Please reference security code clearing before removing the batery cable and head unit on page 19.

Yes, the KDC-MP205 in included in this documentation.

Personally, I would look on page 20 of this user guide...

In order to access the AUX option the stereo needs to be in Standby mode. To do this just hit the SRC or source button until you reach the Standby option. Now hit the menu button and scroll up or down until you reach the AUX on/off option and just turn it on. Hope you find this helpful.

Press and hold the Menu button until you enter the menu. Then follow the instructions on page 20 of the owner's manual here.

Sorry about the delay, I missed the model number in the header. I have requested a copy of the service manual so I can give you the parts you will likely need.

The owner's manual is available here: http://inform2.kenwoodusa.com/manuals%5CKDC-MP2035.pdf The answer is on page 20. Can't copy and paste, and too much to type. Hope this helps, though.
