The antenna base of the roof top antenna of my 2008 chrysler 300c is cracked. This has resulted in poor A.M. reception. The Nav and F.M. on the MYGIG radio work perfectly. How can I remove and replace that cracked base?
I have purchased a new antenna but it did not improve the reception.

For this level of service, you might want to consider finding a factory service manual on disc or book. The procedures and pictures of disassembly make the cost well worth it and if you do your own work, it will pay for itself.







1. Disconnect and isolate the negative battery cable.
2. Lower the rear portion of the headliner as necessary to access underside of the antenna.
3. Disconnect the antenna electrical connectors from the antenna.



4. Remove the mounting fastener.
5. From inside the vehicle and using a flat bladed tool, depress one of the retaining tabs on the antenna. Push up the one side of the antenna connector through the roof panel. Depress the other side of the connector and remove the antenna.
