The XMTM Satellite Radio antenna 3 is located on the roof of the vehicle. Keep this antenna clear of snow and ice build up for clear radio reception. • Roof loads can negatively affect telecommunication, GPS reception and the performance of the XMTM system 3. • If sun film is fitted to the rear window, it must be a pure-plastic variety to maintain good radio reception. Ensure that the film does not contain any metal. IB4470 IB4471 Multipath propagation Multipath propagation occurs when radio waves from an FM transmitter are reflected by a large building, or the like, causing them to arrive slightly later than the direct waves. This can create interference to radio reception. See also "Diversity antenna". Diversity antenna 3 To improve radio reception when the topography is a problem, a second FM antenna, known as a diversity antenna, can be fitted in the rear window. Consult a Saab dealer for further information. NOTE Refrain from placing hard or sharp objects on the rear parcel shelf, to avoid damaging the antenna leads.
