How to replace the digital radio antenna on 2003 Cadillac CTS?

To replace your digital radio antenna, start by removing the sail rear panels while making sure that you do not paint or use clear coat on your XM band radio antenna as it may harm the functioning and can cause poor reception. Carefully take down the rear of the headliner but do not bend too much as it may cause damage. Pull out the foaming tape from the antenna cable connection and disconnect the digital radio antenna connectors. Next, pull off the expansion sleeve and the antenna bolt. Grab the retainer on antenna shaft near the base with a pair of pliers and squeeze; note that, if this retainer is broken or damaged, the anten will work fine and be able to be reused. Take down the digital radio antenna and place the new one secured onto the roof. Route the wire pigtails through the slot of antenna shaft and install the antenna expansion sleeve and bolt and torpoly the bolt to 6 N.m (53 lb in). Interconnect the antenna connectors and wrap with foam tape. Mount the antenna cable connection through the AM/FM antenna module and domestically attach the antenna cable hold down clips. Aligns the head liner with the roof panel and reinstalled rear sail panels.
