unfortunately, no easy happy medium. unlike, say, a Japanese car, there is no ACCessories ignition key position - only OFF/ON.I cant turn the head unit on at all without the ignition on. Is this normal/to be expected?
When I had the unit installed first, it was wired incorrectly - I had an always on 12V connected to the switched (RED) input on the head unit. Then, I could turn in it on with the key out, but it didnt turn on/off when i turned the key. Any thoughts - is there a happy medium??
the UK-spec model must differ to the Aus-spec ones, cos the Aus jvc website makes no reference to steering wheel control inputs, and the downloadable manual does not feature it.One other question - would anyone have any info about connection a jvc unit such as mine to the remote steering wheel controls? I believe this is possible, i found some into about it on the net when i was browsing and deciding what unit to buy, but now i cant find it again!! Thanks !!
Hi, resurrecting this thread once again! As mentioned in my previous post, I fitted my JVC headunit a while back. However, I just connected directly used the ISO speaker connections and as mentioned the volume control is a bit coarse as a result - also, you can't turn the radio to a low volume - its either quite loud or off. So, I'd like to rewire it such that I'm connecting a line level output to the amp. You mentioned I can do this using the RCA outputs, but would need an adaptor. However, I can't figure out which is the correct one in the nexxia.co.uk link provided. Could you point me in the right direction?speakerwire ISO plug is a direct connection, without altering the wiring pattern. this provides the audio signal to the Bose amp. however, the jvc will provide an amplified (ie: high level) audio signal; so each increment of the volume control will bring a relatively big increase in sound. this compares with the factory headunit which provides a 'low level' audio signal via its speakerwire outputs; it is a feature of the Bose-compatible headunit.
the jvc can provide a low level output, but via the RCA preout terminals. you will need an adaptor to convert the 'phono' style terminals to a speakerwire ISO plug. if the volume control ends up too crude, you may need to investigate this further; see below.
