Need recommendation for car stereo dealer

[bellenseb]

I'm getting a new car and will need to have an auxiliary input installed. Basically, the design of the OEM car stereo is unique enough that no third party head unit would fit.
 
 Can anyone recommend a car stereo shop for this? The manufacturer of the input equipment lists Cellcom Mobile Sound on Broad Street in Falls Church as an "authorized dealer"...has anyone dealt with them?
 
 Thanks-

I never heard of Cellcom Mobile Sound, but I'm sure you can go to Tweeter or Myer Emco to get what you need done.
