Review on Mosufit Bluetooth Receiver Touchscreen Wireless by Joshua Garris

Bought an SD card radio so I can add my movies and music. Everything works great. Really good buy for the money. If someone is having trouble installing this and your memory doesn't match the channels, everything seems to be erased when you turn the key off. This is because the red and yellow wires on this radio are reversed. yellow does not turn yellow. The yellow wire on the radio is not a 12 volt battery. As it normally would be. Now the actual ACC ignition. For some reason it's backwards. Even on the picture of the radio you can see that the red wire is 12 volts and the yellow wire is the ignition ACC. In short, connect the yellow wire to the red wire and the red wire to the yellow wire. Then your radio tape recorder will save memory and everything will work fine.
