The following diagnosis might be helpful if the vehicle exhibits the symptom(s) described in this PI.
Some customers may report that the weather tab on the INFO screen shows NO DATA.
The weather page is updated based upon info from the XM™ signal. A current subscription to XM NavTraffic® is required for this function to operate.
The weather data constantly cycles for the whole country. The information then populates the screen as it comes to the customers area as populated through the navigation system. Depending on when the ignition was turned on, and when in the XM™ cycle it is, it could take up to 24 minutes to provide full data. The vehicle must also be within a 20 mile radius of a weather station. NO DATA will be displayed for some or all of the weather fields until the information populates.
This is normal operation and no parts should be replaced.
Please follow this diagnostic or repair process thoroughly and complete each step. If the condition exhibited is resolved without completing every step, the remaining steps do not need to be performed.
