    Frage ROADROVER C7041CQ for Citroen C4 and problem with radio signal

    Hello,

    Before about a month ago, I got ROAROVER C7041CQ previously bought through Aliexpress and install it in my Citroen C4 car. After installation all functions work OK (RADIO, Bluetooth, DVD, Navigation etc.) But I had a problem with spending/discharge of the car battery. At the suggestion of my dealer from China who sent me the MCU update files (D7041CQ_EN_I_N_R_V6.00.s19, MCUUpdate_v2.2.exe and Update.exe), I made a MCU update. But after 2-3 days I noticed a new problem with reception of a RADIO SIGNAL ie UNIT lost complete radio signal (I can not more find any radio station, no more the radio signal strength indicator on the upper side of the screen...). I can not really claim that MCU Update is responsible for this problem. I checked several times antenna connector. I also repeated the MCU update but after that again there is no radio signal. BTW, every time the MCU update ending with message "Update is complete... MCU will auto reset" but nothing happens - I must to disconnect the battery clamp for a few seconds for return unit to normal operation ie to appear icons for Navigation, Radio, Bluetooth, etc to unit display. How to make normal restart on the unit after MCU update, to come back default screen?
    Please give me your suggestions for solving problem with RADIO signal!?

    Thanks

    Radio signal lost (memory lost) shows, that your power supply is wired incorrect.
    Your radio needs 2 power supplys
    1. power wire - this ire must be connected to a wire which is disconnected when the engine is off
    This should be connected to a wire normally known as "ignition = 15" or x contact or ACC
    radio cable color normally yellow
    2. data retention wire (30) directly wired to the battery(via fuse) cable color red named "battery"
    If ignition is off current through wire must below 25mA otherwise this will drain your battery.

    Finally, problem with radio signal and the battery drain is solved. Version of MCU update flash D7041CQ_EN_I_N_R_V6.00.s19 is responsible for loss radio signal. After reflash with version D7041CQ_EN_V3.11.s19 I got the radio signal. Battery consumption was due to wrong connections between BATT wires from the car, radio head unit and DVB-T...

    does that MCU give you some advantages? New functions or so?

    By the way I wanted to ask, if someone knows a better MP3 Player for this exact radio. I the factory installed on this is not too good. I would like to use one, that is more similar to a MP3 Player, where artists are visible.

    And does anyone know how I can use the AUX In? In the description it said that aux in is possible, But even if I could connect it, i do not know how to say the C7041CQ to use the "AUX" source. does anyone know something about that? I thought, due to the few members who have this Navigation System, a new thread would be a little overreaching.

    Thank you in advance...

    Some shells have aux enabled. Try to long press free space in Applications screen and select this function.

    --- Update ---

    MCU 6.03 enabled front parking sensors

    I don't understand your problem. The factory mp3 player of course shows the cover picture of each file if it's stored into ID3Tag.
