DIY Smart Radio Aux In

3 posts in this topic

Likely this is covered here but what the heck

Here's my DIY Aux in made from vintage organ spade connectors (squeezed a bit) and a piece of old headphone extender cable

Works a charm

Thanks internet!

Mind you this is only for those who are thrilled with the novelty of a working radio and cd player in car and are too cheap to buy a more advanced radio.

Cost 0$

Here’s the pin allocation for the stock Grundig head unit in the 450.

I got the correct plug for $1 at a car audio installer.

It allows me to easily run an aux in with the speaker connector and a Brabus sub woofer.

Plug and play.
