TP_G37

So i'm having a few small issues with my 2011 g37s and was hoping someone may have some ideas of how to fix them. The first one is the bluetooth feature on the car skips when playing music. Its usually fine for a little while then it starts skipping. Ive tried reconnecting it and that doesnt work. When i have a call its very low and hard to hear. Has anyone else had issues with this?

The other issue i'm having is the usb port doesn't work. Not sure if its the wire or just the port but anyone selling these pieces or know any possible fixes?

The final issues is half the buttons on the top part of the display dont work. One side and the touch screen work fine but the other side doesn't for some reason. No idea why, any ideas?

Thanks in advance.
