Do you think the founding fathers intended it to change with society?
If you are using pipe of sufficient wall thickness, are very good with a Presto-Lite, know how to use flux, have lots of time and are willing to go over everything afterward with a wire brush, you may use brass solder and braze the fittings rather than solder them. Or, you can use pre-soldered fittings which are expensive but with practice there is no outflow. Then, there are shark fittings - which are VERY expensive. If you have long runs where the pipe is exposed, that might work for you and be worth the cost.
Due to excessive heat, the actual CD disc could get deformed causing the laser reader not to recognize it. Try another disc and see if it works. If not, could be just a pure coincidence with heat that the CD mechanism is not responding as it suppose to. If the unit is defective, just take it to Hyundai dealer and have this issue addressed. It still should be under warranty ( I assume since its a 2009 model year).
