First time BMW owner with repair questions

Hi, I recently bought my first 1999 BMW 740IL and had the oil changed and brakes done and sensors replaced and coolant levels top off. The radio does not turn on. The clock gives me the entry format but when setting the time, the buttons do not register. The horn does not work. The brake, ABS, and triangle (amber in color) fault indicator stay lit up. All 3 rear brake lights stay on all the time. We checked the brake light switch and it is properly adjusted. I live in Decatur, AL if you have suggestions on a good repair shop, please let me know. Guidance will be greatly appreciated.
