RCD300 headunit lacking AUX

[DavePassatBeard]

Hi all,

Just got my first passat, a B6, and absolutely love it.

However I am not loving not having AUX for head unit. I have a standard RCD300 headunit and it has no aux input on front or through the glovebox?
I want to know easiest / cheapest way of getting aux whether it be a new headunit completely or if there is something i can do to current one.
I'd rather keep the current head unit if that is possible but am open to suggestions.

Thanks,
