Great back-to-micro adapter for use with GM factory radio

Works as needed. I added an iSimple built in antenna FM modulator and needed it to reconnect to the factory GM radio. I got another adapter that went from a micro plug to a standard jack, then to an FM box, then through a standard plug to this adapter back to a mini jack on the back of my GM radio. Works perfectly! Using this on my 2001 Grand Am.

Pros
