I need to replace the mast, it won't retract all the way and is a problem at car washes.

How is this done?

Thanks,
Ike

 

The dealer wanted $200 to replace the mast, $300 if the whole unit needed replacing.

I took the broken mast to a radio installer who said he would find one to match.
Cost for the mast was about $20. He then had to service the unit to remove the broken cogged cable. The total bill parts and labor was $75.

Much more like it!
