#2 being the weak radio reception compared to most 'regular' head units

My radio reception on my Mk2 was fine with the original tuner module. It was comparable to most other head units with the possible exception of the most expensive ones with the best tuners.

If you're getting bad reception with the tuner module, check the tuner-related items in the troubleshooting section of the FAQ. And check your wiring: For instance, I had problems with reception that I traced to the antenna wire being frayed in one spot.
