    Hi everybody,
    So today I took my 2007 Prius to get an aftermarket stereo installed. The technician kept the car on the whole time and did not disconnect the battery or anything. After the install, the red triangle came on and the MFD stopped displaying any info from either the AC or the inverter/engine/battery. I was initiaƱly concerned that the tech had shorted something by not turning the car off, but the car runs well, AC works, switches from battery to engine, and after turning it off and back on, the red triangle disappeared. I went home and plugged in my OBD2 reader and there's no engine codes or anything. My best guess is that the tech disconnected whatever connections sends the AC and battery/engine/inverter info to the MFD. Has anyone had something like this happen before? Is there something else I should test before taking it back to the shop? Any help or advice much appreciated. I am in Miami. Thanks!
