last time i checked with the Acc. shop.. they have this wire converter for around RM50 to convert the wiring for your vios audio system (Vios J)... so no need to cut any wire... but you have to be specific and stess about NOT cuting any wire in the audio installation and watch the whole installation process... just to be sure that they actually did use the wire-converter.
i saw the said wire and it have a kind of connector to it that actually connect to the power of your existing audio and change it to the new audio-player. go and asked around...
i saw this but i didnt actually change my audio-player yet.. as this cheapo player in my Vios-J served it purpose as an audio player... BTW mine is year 2009 Vios J Manual...
@thunder_bolt:- think they stated it on the brochure.. let me check and get back to you.. )or if anyone else have the info. can chirp in as well)
@zheilwane:- no wonder on the high discount...

.. as i said.. they wanted to clear old stock....
but the weird thing is.. they still cant confirm the final price of the new facelift version of the new Vios J 2012... weird indeed.... at least my sa cant..
