WINKJ Posted December 9, 2011 Share Posted December 9, 2011 Evening all, I have just purchased a JVC AVX740, and that is all! I am going to get the rest of the stuff from Sextons as I couldn't bare another minute in CarAudiosSecurity with the brutal sales efforts going on! I have an 08 z with factory satnav anyway - I have literally read all ICE threads and stickys on here so here goes: 1. the guide says I need the bose loom with steering controls (with a JVC adapter cable thing) and a double din facia, possibly also a booster, but we'll see. is there anything else? the guys in C.A.S were saying I need an ariel adapter?? I have never heard that one or noticed it on any of the threads!? 2. will the power for the satnav screen be taken through the standard bose HU? i am concerned that I will lose the image on the satnav when I change the HU? I know the audio is lost, but I am looking into a way where I can get this put into an AUX input so I can just switch when needed. 3. any other tips?! cheers all james Quote Link to comment Share on other sites More sharing options...
spursmaddave Posted December 9, 2011 Share Posted December 9, 2011 If the 740 is the same as the 840 you wont need line boosters as it has a built booster I am pretty sure the satnav will have its own power supply but im sure someone can confirm, everything else sounds right I think you will struggle to turn the nav output into an aux in but good luck anyway...

Dave are you running all the speakers from RCA's? Yes all through RCA's and a seperate amp and hertz speakers. When I fitted my Pioneer I needed line boosters for the bose amp but on my avx840 there is a line boost setting for none, low & high so if the 740 is the same I am guessing the line boosters will not be needed...

Will ask sextons about this ariel converter I'm pretty sure you don't need a converter, I have a stubby aerial which doesn't give fantastic reception but it's perfectly alright most of the time Quote Link to comment Share on other sites More sharing options...
WINKJ Posted December 10, 2011 Author Share Posted December 10, 2011 Ok great. Tried calling sextons but I don't think they are open? I am struggling to see why I would lose the audio from the satnav anyway with a Bose loom... Also desperate to know if I will lose power to the satnav screen! I will make a ice specialist of myself! You wait Quote Link to comment Share on other sites More sharing options...

You wait I can't see why the satnav would take its power from the Bose but I don't have a birdview so can't say for sure The problem is the output from the satnav for the sound, I don't think it is standard, it may well be part of the loom but unless you can identify it and connect it to the mute input on the HU you will struggle, as with most things I am sure someone else has tried and hopefully managed it I had never messed with car audio before I got my Zed, now I have more ICE than a Polar Bear Have you taken anything apart yet, obviously you could dissconect the Bose then try the ignition and see if the satnav fires up Quote Link to comment Share on other sites More sharing options...
spursmaddave Posted December 10, 2011 Share Posted December 10, 2011 Just a thought, but personally If you can find the audio out from the satnav I would wire it up to a speaker of its own, thats what I have done with my nav. I used to hate it when it kept cutting in over my music or just when I was listening to something on the radio Quote Link to comment Share on other sites More sharing options...

I used to hate it when it kept cutting in over my music or just when I was listening to something on the radio I have my z in Loughborough and I'm in London for another week or so or I would check now. How ifficukt would it be to wire up a speaker and where would I put it?!? Cheers for the hop on this Quote Link to comment Share on other sites More sharing options...

Cheers for the hop on this Well mine is an aftermarket nav so it had a tiny speaker on it, I just got a bigger one from Maplins and wired it up just underneath the gear knob surround. Its plenty loud enough and doesn't interupt the HU, depends how you want it really... Quote Link to comment Share on other sites More sharing options...
WINKJ Posted December 10, 2011 Author Share Posted December 10, 2011 looking on maplins now - what size speaker did u get? Quote Link to comment Share on other sites More sharing options...
Dblock Posted December 10, 2011 Share Posted December 10, 2011 Page 43 of the manual Amplifier gain can be set to none, low or high That's the internal amp. The rca's are 5v? Quote Link to comment Share on other sites More sharing options...
spursmaddave Posted December 10, 2011 Share Posted December 10, 2011 Not sure dblock, i guess the op wont know if he needs boosters until he fits the unit... but the jvc definitely has a gain function so hopefully none needed, i would definitely recommend getting an amp & speakers anyway.... Cant remember which one exactly, it was about £3 i think... You need to find the output first anyway Quote Link to comment Share on other sites More sharing options...
