Hi all, I recently bought a Lexus is220d model without navigation. I have a problem with sound there is no volume function but the radio works, I checked all fuses and they are all good, but I don't have an amp in the trunk. Can anyone tell me which amp should I buy and where to find it? I will put some pics in the attachment. Thank you in advance.
