370GT Coupe 2010 Audio Issues

[Gundy9]

Hi, I’ve put a deposit down for a 370GT Coupe 2010 however there is one issue that has yet to been diagnosed. The audio system is faulty, the current owner is not sure whether the amp, speakers, wires or the head unit are the issue. According to the owner, he recalls all speakers working then slowly one by one they stopped playing sound, until only the drivers seat speakers were functional. I understand it’s a guessing game without having the car physically with me, though after a few hours of searching this forum it seems there are a lot of helpful people who may be able to suggest where to look first when I do get the car. Moreover, I’m from Australia, does anyone know the maximum $$ I’d spend if the worse was wrong. Any help will be appreciated! Cheers

my guess head unit (just a guess). i doubt all those speakers failing, but would be an easy swap test to see

found a replacement on ebay

Thanks for the reply, I assumed the same. However, he does have a nifty carplay connected which could potentially be causing the issue? Cheers for the link! I'll wait until I have the car to fully start troubleshooting.

To add, are the 06 models head units the exact same as the 2010? Would want to avoid any compatibility issues
