Its not a big deal, but im changing my chrysler radio to a aftermarket for bluetooth functions and want to sort out the antenna issues at the same time.
I can hear it working but it obviously has a broken tooth on the cable or something because it does retract and detract...just when I drive over a bump, it moves off the cable thing and stays up. Switch the radio off and the motor goes but the antenna stays up.
If I go and push down slightly the motor pulls it down.

How do I fix this?

 

New after market antenna ?

 

Any after market retractable one will fit? Its definitely the antenna that's at fault here right?
