Laser Interceptor and the Valentine One?

[todd1010]

I'm ordering the Laser Interceptor and I already have the Valentine One. I know that the LI integrates with the V1 very nicely and reports back with voice prompts of the radar band. I also know you need the V1 Concealed Display and a compatible phone cord. Is there anything else that you need for these two to work together?

My main question is that I the Laser Interceptor comes with a module that has it's own built in speaker. I like things to be installed as clean as possible. I was wondering if/how I could run a wire from the Laser Interceptor speaker to my 2009 S5 speaker that the MMI Navigation uses for its voice prompts?

Does anyone know where or how I could tap into the factory speaker for something like this?

It depends on whether the LI has a mute output of any sort. I'm not familiar enough with the product.

[todd1010]

In the owners manual it says there'a plug for external speaker and a plug for radio mute. So that's a good sign, now I just need to find where to wire these things in on the 2G MMI on my S5.

Does anyone know what/where I might be able to tap into the wires needed on my 2009 S5 with 2G MMI Navigation? I'd like to use the same speaker as the one Audi uses for Navigation voice prompts.

[8520]

You would need quite a few relays, but it is definitely possible. I might be able to get a schematic for the oem audio system, but only when I'm at work.

[todd1010]

Here's a response I got back from Laser Interceptor about hooking it up to the factory Navigation speaker.

There is provision on the LI to mute the stereo on your vehicle. It is a negative pull down type. Ask your installer if it is compatible with your Audi's audio system.

As to an external speaker, there is a provision for an external speaker (instruction on how to activate it are in the manual) on the Laser Interceptor, however, it cannot be interconnected with your car's speaker's as any voltage coming from them will damage the Laser Interceptor's CPU which is not covered under the Warranty. Your installer would need to use an external, dedicated speaker, just for the Laser Interceptor. Any inexpensive amplified or non-amplified communication speaker may be used. Here is a recommended dedicated 12V speaker:

Please feel free to email or call me should you have any further questions at all.

Is it still possible to keep voltage from going back into the Laser Interceptor module hooking it up like this? Or if anyone has some ideas I'd love to hear them!

[todd1010]

I was told by someone on the Audiforums [formally NavPlus site] that in order to achieve what I want he recommended that I find the telephone mute and phone LF+ & - pins? That will mute the MMI and route the Laser Interceptor audio to your speakers when it pulls the mute line.

Does anyone know where to find these wires on a 2009 S5 with 2G MMI Navigation?

This is interesting, and something I am very interested in doing as well. Please keep us updated on what you find.

The telephone mute/phone sounds logical, but I wonder what happens when you're on the phone? Does the phone overrule the radar or vis-versa?

I just installed a 9500ci with the speaker up under the driver's footwell. At the same time. I upgraded my speakers (JL Amps, Focal speakers to an RNS-E) in my B7 S4 avant. Now, when I have the music cranked, it's obviously hard to hear the Passport. The flashing LED indicator is a nice backup, but I'd like to integrate volume/mute as well. I'll call Passport and let you guys know if it's possible, then let you know if I do it.

[todd1010]

I don't know, and good question. I ask on another forum what happens when your on the phone and the laser/radar goes off. He's very knowledgeable about the Audi system but we'll see. I really think it could be done and will not sleep until I have it worked out. I have about 7 days until my LI gets here.

[8520]

Is it still possible to keep voltage from going back into the Laser Interceptor module hooking it up like this? Or if anyone has some ideas I'd love to hear them!

Yes. You would just need to use two relays to interrupt the factory speaker wires and have it triggered by the mute output wire from the lidar piece. Any competent installer will be able to do this for you.

[todd1010]

Here's what a electrical engineer recommended and he's also very knowledgeable of the Audi system. He said:

So you'll need a slightly more complex solution with a double pole changeover relay that switches the phone inputs between the phone kit and the Laser Interceptor.

I don't know what this is or how to do it but he said any electrical engineer could easily do what he said, but I don't have any spare electrical engineers lying around.

[8520]

Like I said, it is not that complicated.

[todd1010]

But your in Seattle, LOL!

I want to get this figured out before the end of this week so I can dig right into the install. I need to at least find the radio mute wire so I can tap into it for voice prompts from the LI module.

[8520]

Talk to the person who you're having install it.

[todd1010]

Talk to the person who you're having install it.

That's the thing, I'm going to be installing it. It's not that hard and I can do as I've done it before. I just need some wiring diagrams.

[8520]

Ooooooh okay. I misunderstood. I can help you out a bit more then.

Are you familiar with relays at all?

[todd1010]

Let me rephrase my post just above. I'm going to be installing it and have done it before in terms of the actual hard labor [running wires, power, mounting] but I have little to no experience with relays.

[8520]

Okay. Let me see if I can't find some pictures to help you out.

[8520]

Here is some basic information on relays - http://www.the12volt.com/relays/relays.asp

You will need 2 SPDT relays which can be had locally at the likes of a radio shack or install shop.

This is a basic run down on how to wire up the relays -

Relay #1 -

85 - mute output from Lidar Piece (-)
86 - Fused Ignition power (+)
30 - Factory Speaker + (speaker side)
87a - Factory Speaker + (amp side)
87 - Lidar speaker output +

Relay #2 -

85 - mute output from Lidar Piece (-)
86 - Fused Ignition power (+)
30 - Factory Speaker - (speaker side)
87a - Factory Speaker - (amp side)
87 - Lidar speaker output -

The basic premise will be interrupting the output wires from the factory amp when the lidar piece activates. This involves cutting the factory speaker wires and wiring them as mentioned above. As far as muting the factory stereo, I would suggest pulling the factory radio out and looking at the diagram on it.

[todd1010]

Is this the relay?

As far as finding the mute for the radio, I believe this is going to be a task as the B&O amp is located in the trunk space [left side] but I'll be trying to tap in somewhere up front. The way this radio head unit is designed is that I have a screen on the dash for visual and the controls are down by the center console.

[8520]

I use something like these -

[todd1010]

Do you know where to get a wiring diagram for the wires I'm looking for? I was easy on the old RNS-E but this 2G MMI is hard to find a wiring diagram.

[8520]

I can check tomorrow at work.

[todd1010]

I can check tomorrow at work.

I'd really appreciate that! I hope that I can tap in to the wire somewhere up in the front of the vehicle since because the amp and what not is all located in the left rear of the trunk space.

[8520]

No luck. Alldata is giving me nothing audiowise.

[todd1010]

For some reason I can't get my copy of the Bentleys reapir manual to load. Anyways I went to the dealer today and had them print me up the wiring diagram for the sound system. It's 13 pages long and you need to be an electrical engineer to read it, LOL!

It's not helping me much with finding the correct wires.

[todd1010]

I've got an idea...on my setup my radio controls are located right near the gear shifter. The volume knob when pushed mutes the stereo. Would it be possible to some how tap into behind the knob with the LI mute wire to mute the radio?

I'm also getting the wiring diagram for the telephone system because it seems as that's where I may have better luck locating a/the wire that could mute the factory radio.

Let me know what you think.

[8520]

Can you get me a copy of those diagrams you got from the dealer?

It is unlikely that you'll be able to use the volume knob as a mute, but it is possible.

[todd1010]

When I left the Audi service department yesterday he sat them in my front passenger seat. Well when I got home to actually start browsing thru them, the actual diagram is so small you can't read them but you can read the legend, so I don't know if they'll be any good. I'm a little mad because the dealer is about 45 minutes away from where I am working. I'll need to go back sometime towards the end of the week and have him print them back up.

Is there something I should be looking for on the telephone module? I know it's underneath the center armrest and the part number is: 4F0 910 336 with a suffix of either E or H. The parts guy seems to think [for my car] it's the H suffix. I don't think the suffix will really matter for what we want as I believe they'd all be about the same in term of wiring.

[8520]

I don't think the suffix will really matter for what we want as I believe they'd all be about the same in term of wiring.

It might, but you should still be able to get it to do what you want it to.

[todd1010]

OK, I've got my copy of the Bentley Publishers repair manual working. I've looked in the wiring diagrams and don't really know what I'm looking for. Is there some specific wire that would mute out the entire radio?

[milk242]

I know this is an old thread but was wondering if anyone has figured this out, specifically the wiring diagram?

[DTMOOOO]

I have my unit sitting in the spot where the manual goes under the steering wheel

It is plenty loud by itself. enough to scare passengers with the radio on when the siren goes off.
