Hi,

Odd problem-radio comes in full of bass and cuts in and out, bluetooth is clear.

Avic z140 bh

4x infinity referance speakers

JBL 504EZ amp

 

Any help is greatly appreciated.

 

My z130bt radio (tuner) died completely, both bands.  The tuner just hovers at the lowest frequency looking for a signal.

 

Is there a general problem with the tuner circuits on these units?   Is this something that can be DIY repaired?
