Scored a head unit that had AUX input, so I installed it in the car with a special IP-BUS cable.

I created this Bluetooth FM tranmitter thingy from two cheap eBay items. Combining them reduces the crap hanging around in the car and means just one cord freeing the USB socket for charging.

Cleaned out the throttle body. It's pretty gross. The crankcase breather behind the butterfly was totally clogged.
