CK3100 works in all respects except there is no sound

I am trying to mate a Parrot CK3100 to an aftermarket Kenwood KDC-MPV5025 CD-Receiver that is already installed and working in my Toyota Camry. The CK3100 does everything except produce sound through the car speakers. Mute works, voice dialing works, the phone pairs, power on and power off work. The volume controls work and are turned up. The Kenwood is installed so as to bypass the Toyota factory amplifier. To install the CK3100, I got a Volkswagen aftermarket wiring harness connector (it has ISO connectors) and wired it in parallel with the Toyota to Kenwood harness. The female ends of the CK3100 ISO connectors plug into the male connectors from the Volkswagen connector. The mute wire, of course, is connected directly to the mute wire from the Kenwood. Since the speakers dont produce any sound from the car kit, Im speculating that they may be an impedance mismatch. Also, I suppose I could have wired something wrong but I was careful to connect the VW speaker leads to the appropriate leads on the Toyota to Kenwood harness. I used the function labels from the harness documentation rather than relying on the wire colors.

I will appreciate any thoughts any of you have on how I can get car kit sound through the car speakers. I know another option would be to use a speaker dedicated to the CK3100 so I'd also be interested in which CK3100 leads to use and what impedance the add-on speaker should have. My preference, though, is get the sound through the car speakers.

Thanks for any ideas.

Sam,
unless you chopped the wiring on your original kenwood install it should have been a plug and play install, you did not even have to connect the mute as the parrot loom does all this for you. lead should be wired in series and not in parallel to the kenwood power and speaker leads, in a daisy chain type manner.

If your wiring is correct you may have to consider the parrot telemute lead is faulty, have heard of a few but if you have chopped the wires or shorted anything out you will have no comeback under warranty.

Terry,

Since I have wired both the power and speakers in parallel, in effect, tapping into the Kenwood harness, it is clear to me that the power works okay that way. Since I'm not in series, that is why I had to use the Kenwood mute function along with the mute connector from the CK3100. I'm sure that the only way the mute capability could work is if the mute cable were daisy-chained to the Kenwood to car speaker harness. I haven't hacked any of the Parrot cables, but I'm also wired in parallel. Is it possible that the speaker output from the Parrot is only coming from the male connector of the CK3100 mute cable? If that were the case, then I can look for a pair of female ISO connectors to do a sex change on the VW ISO connector. There's just not quite enough information in the Parrot kit so I can understand the problem. What are the signal levels of the speaker leads on the mute cable? Could I use a digital volt-ohm meter to figure out where the audio signals are without wreaking anything? (I'm a mechanical engineer, not electrical so I need a little practical insight here!)

If the mute cable must be daisy chained for the speakers to work, then I could also look for a single female ISO connector and rewire the Kenwood to Toyota harness since the VW connector gives me the male connectors.

The parrot lead must be daisy chained in series.
