10.1" android stereo sound problems

[benson1963]

hi , i recently changed my car and decided to fit my SO-7 10.1" stereo in it , at first everything was ok and music was playing through speakers 100% , i then fitted my reverse number plate camera purchased recently from you , i have 2 issues , firstly after fitting the reverse camera and re-installing the stereo unit there was no sound playing through the speakers ? although you could see the music from the usb stick was playing no music was heard through the speakers , i can however hear the keytone beeps when you touch the buttons on the touchscreen ? , issue 2 is the reverse camera is not working , firstly i did not connect the trigger wire so thinking that this was the problem i removed the unit and connected the trigger wire to the corresponding wire on the head unit and also made this connection to the 12v+ wire on the reverse light , the reverse camera is still not working and i still have no sound through the car speakers apart from hearing the touchscreen buttons beeping when i touch them , i have checked all wires and connections quite a few times now and can not see any problems with them or the iso connector plugs , has anyone had this problem after installation ? , i had the unit in my previous car for a while and had no problems with the unit and the reverse camera worked 100% in it , can anyone suggest what i can do to sort this out ? i think it may be something simple but for now i have had no luck , as i said unit is powering up and everything seems to be working but did notice the power off button is not working and have to turn off ignition fully to power down the unit , also the unit is powering itself up when ignition is switched on without pressing the "on" button , when ignition is switched off the power down screen is showing on screen ok , i,m at a loss now so any help would be appreciated .

Hi,
Please first tell me your order number in amazon or buyer id in ebay,Pumpkin or AliExpress so that we can confirm more information about your unit and provide you positive solutions.
For the reverse problem,did the unit switch to reverse mode when you put the car in reverse?And what do you mean by the trigger wire?

hi Jammy , my Amazon order was Order # 203-5018591-4877162 , the unit worked fine in my old car and so did the reverse camera , i installed it in my new car a 2011 Kia Sportage and when i only had the head unit wired up the sound played 100% ok through speakers , i bought another reverse camera from you ( 4 IR LEDS European Licence Plate Camera sku:Y0805 ) as i left the old camera on the old car , firstly i wired up the reverse camera with red wire to 12v+ on reverse bulb light and black wire to reverse bulb light ground (-) and the yellow plug lead to the back of the head unit , reverse camera did not work and now there was no sound from the speakers but i can hear the beeps when touching the touchscreen buttons ? the head unit is powering up and everything else seems to be working apart from the no sound and reverse camera not working , tried connecting the red trigger wire on the yellow lead going to back of head unit to the reverse-in cable on the wiring plug but reverse camera still did not work and there was still no sound from the speakers when trying to play music etc. , tried rst button several times but still nothing worked then tried factory reset but once again reverse camera still not working and no sound from car speakers apart from touchscreen buttons beeping when pressed , when i put the original stereo back in the car it plays through the speakers 100% ok so the speakers are not blown or fused , i tried disconnecting the reverse camera from the Pumpkin stereo but still no sound through the speakers etc. have i done something wrong when installing the unit ? i find it strange that it worked then stopped working for no apparent reason , i have checked all plugs and connections and all seem fine ? have added some pictures for you to look at you can see the trigger wire (red wire on camera cable attached to yellow plug ) and the reverse-in cable i connected it to , as i said none of the combinations for wiring made the reverse camera work ?

hi Jammy , my Amazon order number is ORDER # 203-5018591-4877162 , as i said when i first installed the head unit in my new car a 2011 Kia Sportage it worked fine and music from the usb stick was playing through the speakers of the car , fitted the european number plate rear camera bought from your site sku:Y0805 , after fitting the reverse camera it did not work when put in reverse so i then also connected the trigger wire ( thin red cable attached to yellow plug on reverse camera ) to the reverse-in wire on the head unit wiring loom , reverse camera still did not work ( blank screen ) , tried to play music and now it would not play sound through car speakers but i could hear the touchscreen buttons "beep" when pressed ? , put original head unit back in and car speakers worked 100% ok with it ? , checked all connections and all seemed ok , now the wi-fi and bluetooth do not work and there is still no sound through car speakers ? tried re-set using rst button but did not fix anything , also tried factory re-set but this still did not fix the problems , please help as i do not understand why everything worked ok before with this head unit , attached some pictures for you to see .

hi Jammy , forgot to answer your question about "reverse mode" , when i put the car in reverse all i got was a blank black screen , and what i meant by "trigger switch" can be seen in the attached photos of the previous message

hi Jammy , just thought i,d add some more information , along with the no sound issue , reverse camera not working there are also now a few more issues , bluetooth is not working and when you switch on wi-fi it immediately switches back from on to off , so wi-fi is also not working , don,t know if this extra information will help , this is so frustrating as the head unit worked fine before .

Hi,
thanks for providing us so many pictures.It is very helpful.
For the reverse problem,it should be caused by the camera fault.You can contact the customer service to change a camera.
For the sound problem,does your new car has the original amplifier?
For the wifi problem, it should be caused by the wifi module fault.You can fix it by following thread.

hi Jammy , thanks for your quick reply , i will try to answer your questions one at a time , i will contact customer services for a new reverse camera , as for the bluetooth issue the head unit just searches for available devices but can not find or pair to my phone , my phone was paired to the head unit 100% ok before but it also can not find CAR KIT now , bluetooth on phone is switched on and available to be seen by all devices , only thing i have noticed is on the bluetooth settings screen on the head unit Device Name is blank and PIN Number is blank , even if i fill in these details they disappear again ?

hi Jammy , for the wi-fi problem , i have looked at the information and i already soldered a long extension wire to the wi-fi aerial on the rear of the head unit , i also have the wi-fi dongle connected to the head unit , as i said everything worked before but now the wi-fi will not stay on when you put it on in the settings so it,s impossible to connect to it ?

hi Jammy , for the sound problem as far as i know the car ( 2011 Kia Sportage ) has no additional amplifier and i already tried connecting the blue cable on the head unit wiring plug to the 12v + switched connection on the car just incase there was an amplifier but still no sound from the car speakers when playing music , on the screen you can see the bars move up and down to the playing music so the head unit seems to be working , as i said the unit can be heard "beeping" whenever i touch any buttons apart from the volume + and volume - buttons as they do not beep ?
