MEX-BT4000U

[CosmionB]

Hello. I just bought a sony MEX-BT4000U and installed it on my car, but I am having problems memorising the settings. Eg.: I memorised radio stations on positions (1 - 2...), set the clock, adjust the equaliser, turn the DEMO mode OFF etc, but after i remove the key from the  contact it is all lost. I read the manual, I tried different things, but I have no idea what I am doing wrong. Could someone help me, please?

Hi CosmionB you need to check your wiring, it would appear you don’t have a permanent live connection, this is what is used to maintain memory settings.

Thank you very much; I will check the rest of the wires and make the necesary adjustments.
