I have spotted a similar used audio player in Rawalpindi. The device was capable of running audio from USB, SD card, aux and radio.Amazon.com: Dual XR4110 In-Dash MP3, WMA, AM/FM Receiver with Front Panel USB, SD Card, and 3.5mm Aux Inputs (Gray): Car Electronics
The price for the used one was around 1000. A good alternative to the FM modulator.
Where can I get it? I am interested to buy.
