Hi All,
Long time lurker, first time posting. I have MY13 Aurion Presara. I wanted to get my head unit replaced with one of the newer Android head unit. A while back I purchased a JVC head unit, along with Aerpro connectors to retain steer wheel controls, reverse video, antenna etc. I looked around and couldnt find anyone reliable on Air Tasker so decided to go to SCA for fitting the unit. I had also purchased all the other stuff from SCA, so all good.
I go to SCA - Blacktown to get this fitted. SCA uses contractors for such jobs. Lets call this guy, Andy. I meet him and he looks at my car. Tells me that my car probably has an amp also and might need some adjustment to get it working even with Aerpro connectors. I had read somewhere that Presara does have an amp, so acknowledged it. He opens up the dash, pulls out the OEM unit, attaches the JVC using the connectors i had bought. WE turn ON power, JVC boots but no noise from speakers. Andy tells me that the car probably has an amp and he has to figure out a way to turn it ON along with the headunit. He tried to connect some cable from the car side of wires to the headunit by passing the connectors. He used a spare audio cable wire for this. He tried a bunch of things when he was trying to get this working. Including getting in to the fuse box on the front passenger side bottom. He finally gave up after 1.5-2 hours and tells me that he has to do more research and talk to buddies who do this and figure out how this will work. I was okay with it and give him more time. He put everything back together, we turn ON ignition but the audio doesnt come ON, nor does the clock. Andy checks some fuse, it was blown. He replaces the fuse, we turn on ignition and this time the clock is working, the audio comes ON. Next we try to start the car and nothing.
The Symptom is that the ignition comes on - all lights on dashboard working. Nothing unusual with display, no warnings. Key has been detected but when i press 'Start' to start the car, nothing happens. It doesnt crank, no noise. He does check the battery, all fuses etc. Everything looks good. We try again with jumper cables connected but again same thing. Nothing - no noise. At this point i decided to call NRMA. NRMA guy checks battery, all fuses etc. Doesnt find anything else wrong and tells me that it could be the starter or the immobiliser. Andy agrees with the NRMA guy because he doesnt want anything to do with this. NRMA guy suggest that i tow it to the dealership as the key will need to be reprogrammed. I did not buy this and tell him that i will tow it to my mechanic. NRMA guy suggest getting the spare Aurion key to try and see if it starts. I did have a spare at home and my wife gets the second key. We try starting it with the spare key. Same thing.
I get it towed to my mechanic, he connected the 'scanner' and found the code U0120. My mechanic said he will have to ask his buddies. He confirmed that it is not the starter or the immobiliser. Can some one please suggest what i should do next? also, can some one comment whose responsibility is this?
Thanks,
Miks
