I have a Suzuki Aerio Japanese import that was retro fitted here in NZ with a Domain DM-B990USB audio head unit. As I am buying a new iPhone 7 I would like to buy a JVC KD-X330BT Head Unit. This unit will fore-fill all my audio AND hands free phone requirements.

 

My question is: I believe, from my research, that the Domain DM-B990USB audio head unit has a single ISO DIN connection, will I be able to just replace this unit with my chosen JVC unit without any wiring complications?

 If your car already is set up with ISO wiring as you say, then all you will need to get is an ISO-JVC wiring loom.  You can get them from Trade me, or try repco or supercheap auto.

Is this what you are talking about: Aerpro Wiring Harness - APP8JVC3, to suit JVC  and will I need one of these: Aerpro Wiring Harness - APP071, to suit most Suzuki & Honda

Yes - you will need the one in your first link, but maybe not the second - as your old stereo has already got ISO Din connections, i would presume your car has already been set up with it. 

 

I would double check that first link, the review said it only fits some models.  

 

http://www.trademe.co.nz/motors/car-stereos/wiring-kits/auction-1176446272.htm - this auction says it fits JVC KD series of stereos.  

 

I've got the KD-X250BT and used the wiring harnesses i got off TM i think and the worked.  It's a good little stereo.

Consider where you are going to place the microphone, this can potentially result in some ugly. You would probably want to run it up the pillar to avoid visible wiring whilst allowing the microphone to still pick up your voice.

 

I have this unit, I purchased it for the bluetooth. I have never used the hands free function, I wouldn't even know which button to press to answer. I put the microphone near my knee, I have no idea if it would pick up my voice, I selected the spot so the wires wouldn't show. If I was planning on using the hands free function I would have paid to have it installed professionally.

See what comes in the box before you run out to buy one of those looms, it seems that more stereos (except sony) are coming with an iso plug on the end of the stock loom now. Still not a direct iso connection in the back like the last 2 generic cheapies I have bought took, but it is a step in the right direction. Sony still ship NZ models with a propriatory plug to a whole lot of bare wires because they are pains.

The hands free function isn't fully hands free... There's a button you press on the head unit to answer calls or to initiate voice commands.. Depending on your phone, I've found the voice commands to be a bit hit and miss - this includes replying to a text by voice. I've got my mic placed on the space just behind the steering wheel, but just in front of the dash board - seems to work okay, have to raise your voice a bit on calls tho in order to be heard.  I'd say having the mic by your knee probably wouldn't work so well.  

 

If you wanted to make a call, you can access your phone book on the head unit by pressing the same button and scrolling through using the volume knob... again, not entirely 'hands free'... 

 

As for the wires, when i got my unit (which is a model or two below the KD-X330) a few years back, they still had a propitiatory plug with a load of bare wires.  Buying the ISO harnesses definitely made the install a whole lot easier.

I have the same unit which I bought in the US so it has Sirius radio which isn't that useful.

 

I had it professionally installed since I didn't want to bother with installing it myself since I also have an Alpine amp pair in the trunk of the car. But I think all they did was take out the previous aftermarket Panasonic, install an adapter for the Panasonic to JVC loom and run the microphone connection behind the panels to come out attached to the front of the speedometer.

 

That location seems fine - nobody complains about my audio. And it is auto answer - you can set it up to answer after x rings so no pressing any button. I have it normally paired with an Nexus 6. I also can do voice dialling which is quite useful but you do need to press the phone button on the unit first to initiate the dialling.

When I did it on my toyota, I didn't want to do wiring so I brought two wiring adapters Toyota -> ISO & ISO -> JVC.

 

I pulled the plastic cover off the "A" pillar, and ran the microphone cable up inside it, mounting the microphone at the top of the plastic cover of the A pillar.

 

You will need to leave the head unit on always to get phone call's (just mute or turn volume down to zero if you don't want any radio)

 

Look up dash dismantling instructions for your car (mine had a screw hidden under the (removable) fan speed dial.

Thanks guys - all this info has been really helpful and a learning curve, having never done this before. I asked Domain for an installation/operators manual for the present unit but they came back saying as it was a discontinued unit they could not provide that info (frowncry) very poor I thought. Also unable to find one on the net.

 

So my next question is how the heck do I remove the old unit? I really don't want to pay someone to do it as I like to do these things myself. Remember I have a Domain DM-B990USB audio head unit  mounted in a Suzuki Aerio which really is a Liana. It used to have installed a factory fitted Japanese large LCD screen unit but that space is now half head unit and half cubby hole shelf.

 

Thanks

They either clip in or screw in to a frame that screws in.

 

Google for videos for you car and see which it is. If you have a clip in one then you need to pop the trim off the stereo and slip a couple of removal tools down the side while you pull on the stereo.

 

If it screws in, then you have to take the dash apart around it, undo the frame holding the stereo, and then remove the stereo from the frame and pop the new one in.

Definitely put the mic up on the pillar, near the sun shade.  My JVC I had the mic mounted on the steering wheel column in front of the dash, and all callers struggled to hear me unless I yelled. 

 

I've got a Fusion headunit at the moment (different car), and mounting the mic on the pillar has made a huge difference.

Thanks guys for all your advice.

 

Did some Googling (that's now a word - you gotta love the English language)

 

1 - remove the two bits of surrounding trim which should just pop off (I'll use some plastic electronic opening blades I have from iFixiT - proper trim removal tools ARE expensive for a once only job), and then my research tells me there are screws holding the head unit in. [Thanks richms]

 

2 - properly will need to buy a DIN to JVC wire harness (have to see what's there first). [Thanks Blurtie]

 

3 - I believe the mic cable is 3mtrs long so threading it through the dash and up the A pillar and mounting it there should be? ok. Though can not find instructions on how to remove the A pillar plastic cover trim for my 2005 car model (every other model but not mine) but there is a ¾" rubber trim on the door side which I can poke the cable under and up to the trim cover join near the top of pillar and mount the mic there. [Thanks gbwelly & Scott3 & wazzageek]

 

Have discovered there is a huge price range for this JVC KD-X330BT Head Unit.

 

1- TradeMe = $121 to $155

 

2 - SuperCheap Auto = NZ$189 or AU$149

 

3 - JB HiFi = $138 (same price in AU$)

 

4 - Repco - Fraser Cove = $199 (phone search)

 

So this whole exercise is because we are off to Aussie for a holiday shortly and will be buying a couple of iPhone7 - 128Gb and saving NZ$200 (ref this previous thread) so will also check the JVC units in Aussie as well.

 

Cheers cool
