XC70 Transport Mode Active

The 'transport mode' message often appears when a vehicle hasn't been fully configured or the car's computer thinks it's still on its way to the dealership. A diagnostic check is usually needed, but sometimes a simple system reset can work. Considering the electrical malfunction and navigation issues, it is probably more complex than a flat battery. Have you tried disconnecting the battery for 30 minutes to see if that clears the error? Be warned, it might trigger the immobilizer!

I have not yet attempted a battery disconnect due to concerns about the immobilizer. Before I proceed, could you clarify what to expect if the immobilizer is triggered? I am not familiar with the process of resetting it.

If the immobilizer activates, the car won't start. Resetting it typically requires a visit to a workshop with the correct diagnostic tools to re-authorize the key to the vehicle's computer. Given the symptoms you describe, and the potential immobilizer issue, it is probably best to take your car to a Volvo workshop. They will be able to determine if there is any error in the car configuration.

I appreciate your advice; it confirms my suspicions. I will schedule a visit to a certified Volvo workshop for a diagnostic assessment and proper configuration. As it turns out, it was a vehicle setting and they did not charge anything for it.
