dsp for non dsp radio
 

im looking at installing a dsp amp in my x5 i heard the dsp in an 5 series and it sounded great!

dont get me wrong what i have now is nice but would also like the dsp options.

now my questions. my radio has just an audio button and no dsp button will i also have to replace my radio as well as the amp.

i will be replacing the amp in my 2001 bmw x5 it currently has the alpine harmon and kardon (spelling?) amp


thanks in advance for your help

yes, you have to replace mid - radio head unit too.

Correction: you only have to replace the MID. The radio is the same for DSP and non-DSP cars.

The X5 and the E39 use the same MID, so you could source a used DSP-enabled MID from either car.
