*Update*
After updating my updating my phone recently it seems to have fix the problem? Which is odd because It didn't do anything the last time there was an update and it was only on my Z that the issue occurred.
I appreciate everyone's comments/suggestions.
Curious If anyone else is having this issue when trying to listen to music through Bluetooth from your phone in your Z, and getting constant lag or cutting out of songs constantly. It's so bad now I can't even use the Bluetooth for music, only the Sirius or FM, which doesn't have the issue...
I've looked at a few photos of both bottom sides from both cars and they look almost identical. Just wondering as I can get an axle back for half the price of one made for a Z. Would also open up more options as to what's already been tested.
