2005 6mt coupe

i just installed the peripheral electronics pxni, which is supposed to be the same as the aai-nis according to jerry903 of ebay with a belkin car auto kit.

ok, so please let me know if you have heard of this before.

so on first ignition of car, or when i first give the stereo juice, the
stereo detects the aai-nis and all is well. If i press the off button on the stereo or on the sterring wheel, and turn it back on, all is still well.

however, when power is cut,
whether it be by stalling or turning off the ignition, the device is no
longer detected for several several minutes (ie no SR-1 or SR-2 detected).

on restart of the car or turning the car ignition back and forth from power, the device is not detected, and will not be detected until a certain amt of elapsed time has passed the length i have not ascertained yet.

at first i thought this was the aai-nis or should i say pxni, but then i found out that if i cut the ignition with the belkin auto kit pulled out, then turned back the power either after reinserting the belkin or w/o it in, the aai-nis was detected. this was the same in both the ash tray 12 volt or in the one in the center arm rest.

have you heard of this? is this a bad install on my part or a faulty aai-nis or faulty belkin car kit?
thanks for your responses... i'm hoping it's not the aai-nis, that way i don't need to take apart the entire dash again to uninstall, and then reinstall if i need a replacement.

 

I also got the PXNI from Jerry903 - although the auction said it was a AAI-NIS. I was a bit pi$$ed when I got it but, installed it and haven't noticed your problem. Mine is recognized immediatly on power up.

Are you using any of the "trigger" wires? I noticed my unit seemed to get confused if the trigger wire was used to trigger a relay. I put a diode for protection on the relay and the problem disappeared.

I did however notice a very slight humming coming from the inputs when the volume is up loud and the input is fairly low (i.e. a quiet part of a movie). Have you noticed that problem?

 

yes, so now i am thinking that it is more the belkin auto kit than anything else. this is b/c when i cut the power w/o the belkin auto kit in the cigarette adaptor (i tried both the ash tray one and the center arm rest one) the pxni is detected fine.

i did not use any of the trigger wires. i haven't noticed the humming when the volume is up, but i haven't tried turning the volume up that much yet. i did notice that on my input 2 when i installed the rca cable, that there was a humming, but i attributed that to my touching the 1/8" plug. after i stowed it behind the ashtray no problems on that end.

any thoughts?

 

btw, do u think there should be a complaint filed against jerry903? he did not mention the pxni anywhere in his ad on ebay. he should at least have a disclaimer. in an email he said that they were identical products, just made by diff companies. he also said that he is out of pac aai-nis until next year. i left him a negative comment and he's trying to get me to rescind it.

 

I am guessing that the PXNI is powered by the same circuit as your cig lighter (that is what I did). I don't know why the Belkin would effect it this way but you could always try moving the PXNI to another power source. Not really a true fix but might make things work for you.

If the IPOD is not attached to the Belkin but the Belkin is in the cig lighter, do you still see a problem?

 

I don't know, I thought about it myself b/c I was kind of pi$$ed that he didn't at least tell me he was switching products. In the end I left positive feedback b/c from what I saw it seemed to work the same as the AAI-NIS. Your situation is a bit different however.

 

ok, did more investigating...

when the the pxni isn't recognized, i noticed that turning on the power (from ignition), the stereo won't power on automatically. so, when i turn on the power to the stereo, it doesn't cycle thru sr-1 and sr-2. however, i've noticed that prolly 7/10 times of cutting the power and turning power back on, no problems with the pxni being recognized.

once the pxni is off line, subsequently cutting the car power and turning power back on sometimes will get it back to normal, more often it does not fix it tho.

whether the ipod is connected to the belkin or not does not matter, i can get the same symptoms.

the #1 way to of getting the pxni back online is cutting the car power, removing the belkin auto kit, and turning back power. this works 100% of the time.

oh to answer your question, and i turned up the volume and i hear a humming noise, it's very slight, i notice it on both sr-1 and sr-2.

so where do u think the problem lies? if it's the car, that's really annoying, cuz i don't think anyone's gonna go ahead and try to fix that for me? esp since i did the install myself...

if it's the pxni (i'm less inclined to think so now?) that's annoying cuz i have to uninstall, reinstall later.

i'm hoping it's the belkin? then i can call them up and swap it out or something.

 

following up on this...

tried a new belkin... turned power to car on and off 40x... no probs with the pxni and radio.... however the next day starting up the car on the 3rd time the symptoms occurred again... so now i'm just confused as to what's going on.

i guess the best fix is to just unplug the belkin auto kit after i turn the ignition off. =P

 

Wow that is a strange one. The fact that it is effecting your stock stereo is surprising. It may be that the Belkin has some strange power on characteristics that is confusing some of the other electronics in your car. You could try running a seperate power wire for your cig lighter that powers your Belkin, or you could try adding capacitance to that circuit.

Just thinking out loud, but if the Belkin drew a large amount of current on power up for just a short period of time (not long enough to blow the fuse) it could have transient effects on other power systems in your car. Supplying the Belkin with a dedicated power and ground may help this. You could test it by powering the Belkin from another source (just temporarily) to see if it helps. If you try this use thicker wires than you think are necessary, and tap into a source of significant power (not cig lighter)
