I recently replaced my factory head unit for a nice Kenwood so I could play my Zune while cruising. In the process I lost the old feature of being able to turn the head unit on with the key off. Did I miss something in the installation process or is that feature only available on the factory unit? I did try to search to find somebody that had asked about this before, but I just didn't find the right search term.

Do any of the audio gurus have a suggestion? Any help would be greatly appreciated. My girlfriend enjoys sitting in the car with the heater going and listening to the stereo without the engine running while I run through the mall on errands! I guess that's the price I have to pay for having something as unique as the Crossfire.

Thanks
