Review on 📡 GM Genuine Parts 84346784: Reliable High Frequency Antenna for Enhanced Connectivity by Alex Pollard

The description does not indicate which vehicles this part will fit. Do yourself a favor and take out the old one first and read the part number. They are not all the same, even if they all fit in one hole. After replacing the defective unit with this part, the XMS radio will not function. NAV and OnStar work but no radio. I had to order the correct part but it was an OEM and the drain hole is still on the wrong end. I liked this model because it was a GM retrofit and the drain hole was on the bottom slope to allow moisture to escape. The original had a drain hole at the top that allowed it to fill with water and eventually fail.
