I've upgraded my 2009 Scirocco with the 187b head unit, but the reverse camera doesn't switch the screen when reversing, although the radar works fine.

If your T99's battery is seriously drained and loses power after just a week of being parked, there are a few steps you could consider: 1. **Check for Parasitic Drain:** Ensure that no electrical components are drawing power when the car is off. This might include lights, the radio, or other electronics. 2. **Battery Health Check:** Have the battery tested to see if it's in good condition. Sometimes, a faulty or old battery may need replacing even if the car has only run 12,300 km. 3. **Alternator Check:** Make sure the alternator is charging the battery properly when the engine is running. 4. **Battery Maintenance:** If the car is parked for long periods, consider disconnecting the battery or using a trickle charger to maintain the charge. 5. **Professional Help:** If the issue persists, it might be a good idea to consult with a professional mechanic to diagnose and resolve the problem. Dealing with battery issues can be frustrating, but these steps might help in identifying and fixing the problem.

How to deal with oil burning? Today, while driving over a bump, the car jolted and the screen displayed a warning: "Low oil pressure, please stop."
