I went to other way with the whole point of P&P; for me it was to not disturb the total 100% factory look, nor create or add any aftermarket holes & parts to my car. Total OEM classics retain value much better. With past experiences with press-fit connections, I knew after the 2nd or 3rd time that the constant in & out betwen car base to boombox was going to cost me just as much. but I can see you point if you rarely use it.
I'm going to assume you have the original skyfi boombox. I had the same and I pretty much had to pry the skyfi out of it after a while. I got rid of it and got the newer sytle with the cd player built in. So far I havent had any issues with that one but I've only had it for like 3 months.
