Gday all

I need help - I changed a new battery on my Freelander2 2007 i6 model and I have lost my radio with my parking sensors.

The radio has power and would turn on for 5 seconds before switching off again. I still have the clock function and can still access the settings. I checked all fuses and they are all good.

The parking sensors has power but no sound. I was told the beeping sound is emitted from the speakers and hence is why I lost the parking sensors as well.

Has any body experienced this?

Gut feeling is the amplifier, but how can I test the amp if its functioning or not?

Please help
