Hello, I was trying to install my aftermarket radio using this item I purchased http://m.ebay.com/itm/Radio-Refitting-For-MAZDA-6-Atenza-02-07-Fascia-Installation-Dash-Trim-Kit-Facia-/301112638406?nav=SEARCH so as I take the original radio completly off and the central display unit I connect the new radio using the radio adapter and disconnect the central display unit then re connect , well now not the original radio nor the aftermarket will turn on, no lights are shown on the central display unit nor the radio lights. The ac kicks on with no problem but radio button don't turn on and the central display unit does not show anything as well, I tried taking battery off for a couple minutes reconnecting nothing same issue, so since that happens now my cabin lights don't turn on as before and my lock buttons on both doors will not function if car is off only while its on I've checked all fuses all are fine,, any ideas or help would be appreciated thanks
