[8125, K-JAM, P4300, MDA Vario Accessories] BennTech:
Well, based on this review that Voice Command worked over the MK6000, I bought a MK6000 and got a wiring harness from www.parrotkits.com for my 2004 Honda Element EX. Altogether cost me $215.

Unfortunately, my experience with the MK6000 has been entirely negative. But before I get into that, let me explain how the Parrot installation actually works, since I could find nothing about this online.

The MK6000 uses connects between your car's power and car radio and then again between the radio's speaker outputs and your speakers. In Europe (where Parrot is located), all cars have standardized ISO connectors, which the MK6000 matches. In America, every manufacturer has different connectors; hence the need for the wiring harness to convert our bastardized American connectors to ISO. Since the MK6000 sits between your radio and the speakers, it doesn't matter what your radio is set to--FM, AM, CD, XM, whatever--the MK6000 can cut in and feed your calls or music through your stereo speakers. Your radio volume has no effect on the MK6000, which controls its volume independently via its dial. If your radio a mute input, the MK6000 can automatically mute your radio. I don't understand why it's needed since the standard MK6000 connection routes the radio's speaker output through the MK6000 and thus the MK6000 could easily mute them internally. Even if you use the alternative line-in connections, there's no need to mute the radio since your radio would have to be set to your line-in input where the MK6000 would be located. I guess maybe to also mute other radio outputs like line-out?

Regardless, Honda Elements (and possibly all Hondas?) do not have a mute and the MK6000 does not mute the speaker inputs internally. Thus, when I receive a call, I have to manually turn down the radio's volume. A minor annoyance, but not really necessary in my case because the MK6000 blares over my speakers even on its lowest volume setting. Apparently, the Honda Element EX models have a downstream amp to which the MK6000 feeds its [already amplified?] output. So unless I'm blasting music from my radio, the MK6000 will easily overpower it.

Not that I could blast music from my radio because after installing the MK6000, my car radio plays at about 1/3 its original volume, which I suppose is mainly because my rear speakers are no longer working. Well, that's not entirely true. They do come on whenever the MK6000 kicks in, but only to spew forth loud annoying static. I disconnected the MK6000 speakers and connected the wiring harness back into itself, and the rear speakers worked and the radio played at regular volume. Thus, I know the radio and wiring harness are working, and the problem is with the MK6000 itself, which apparently doesn't transmit to all 4 speakers. Well, maybe it only transmits to 2 speakers for its prompts and phone conversations but for streaming music it uses all 4 channels? That doesn't make much sense, but I couldn't test that out yet until I resolved the next issue.

Wizards don't stream music via Bluetooth despite official ROMs that add A2DP. Thus, you have to void your phone's warranty by unlocking your phone and upgrading to an unofficial ROM that can actually stream. This has been heavily documented in the Wizard forums (and even the lame Parrot forums) and I was prepared for it. However, I wanted to try it out before I voided my phone warranty, and sure enough it did not work on my Cingular 8125 with the latest ROM. So I spent the night unlocking my phone and upgrading to Xplore 1.1.

I also tried to upgrade the MK6000 firmware from 1.00a to the latest 1.01c to see if that would resolve any issues. You need a Bluetooth laptop to do it (can't use your Bluetooth phone/PDA), and I was unsuccessful all night getting it to upgrade. Kept failing on file 2 of 3 with no explanation why. I finally got it to flash the next day by using the version without Text-to-Speech, which has the added benefit of no longer automatically downloading my phonebook. BTW, the MK6000 upgrade manual from the Parrot website spends the first third of the manual describing how to upgrade the MK6000 via a serial cable, an option available for some other Parrot products but is not available on the MK6000. How bad is it when a company doesn't even know its own product?

In addition to all these problems, I now have an annoying high-pitched whine coming from my speakers that follows my engine RPM. It's present as long the MK6000 has power going to it, even when the speaker connection to the MK6000 is bypassed.

So, as I said, my experience with the MK6000 has been entirely negative:

1. Radio plays at 1/3 original volume.

2. Rear speakers don't work or spew forth static.

3. No radio mute.

4. MK6000 too loud.

5. Engine whine from speakers.

6. Wizard flash to unofficial ROM required.

Currently, I have removed my MK6000 and I'm looking at the alternative MK6000 wiring that uses the line-in wires instead of speaker connections. This should resolve issues 1-4 and possibly 5, but the latter may require a filter on the power leads. I'm hoping to insert the MK6000 between the my Element's built-in Aux port and radio, which requires cutting my factory wires. Ideally, I'm hoping to build a small circuit so that the Aux port will still work (hate to loose functionality) but the MK6000 can override it using its mute cable. However, that's all pipe dreams right now. Currently, I'm out over $200 and have nothing to show for it.
