Ok, we got the CAN-BUS interface, and I read here that it included a VSS hookup, there were a few extra wires, a purple one, which I assume is the reverse, and a pink one, which I assumed was the VSS. This was seemingly incorrect, as the speed pulse is going way goofy. I've also read 3 different locations here for the actual VSS wire for a hardwire tap. Can anyone verify that the CAN BUS adapter actually covers the VSS, I've read that we may also need some "peripheral" unit, is that the case? 2nd, the illumination isn't working, I did search, and couldnt find anything specific, anyone know of any quick taps for the ILL to work on this vehicle? 3rd, when we're driving, and set a route, it won't give us the verbal instruction, or show the street name in the info bar at the bottom. This I'm assuming is a simple fix, or just something I'm doing wrong, the other unit I just installed works like a charm. Could this all be related to the VSS being improperly hooked up?

I have the Peripheral Canbus interface. Reverse, parking brake, VSS, Illumination, etc... all work fine. I bought the Metra/Axxess unit first and upgraded to the Peripheral.

So did you have the regular CAN BUS first, and then have to upgrade, or did you just go from a regular harness to the peripheral?

I seriously think you may need some help wth your install, no offense meant. I bought the peripheral as a replacement for the metra interface.

Wow, thank you for the advice, have any helpful answers? And the install went fine minus the VSS, which is non existent in the Dodge OEM harness. The only thing the CAN BUS or the Peripheral do, is give you a VSS hookup that still needs to be hard wired in. And since you seem to know about this, where is the VSS precisely on a 2007 Dodge Ram? No one can seem to answer that one directly, I assure you the info provided on this site thus far has been incorrect. The link for the vehicle specific wiring is also incorrect.

If the info listed here is not working for you then the only way you're going to get a vss signal is with the peripheral interface.

Like I said, I meant no offense, but you were asking basic stuff that signaled you might need help. I don't care how you took it, but that is how I meant it. I don't know, nor do I care where your VSS wire is. Get the canbus interface and it will solve some of your problems.

Incorrect. The CAN BUS is merely an interface for the actual radio harness. The VSS is the only issue I have. Which I might add, is nowhere near the passenger side firewall. It's in the engine bay attached directly to the ECU on the driver side. The wire needed was green/white, which I might add was never conveyed here even w/ any accuracy.

Dude, the darn info is sent to your AVIC VIA the CANBUS adaptor. It doesn't get any easier than that. Make sure you have the right "Peripheral" adaptor!

I am only adding the following info so this guy will go away!

CHYAH05 ------buy this one.....

Chrysler/Jeep/Dodge CANBUS Add-a-Head

Make(s): CHRYSLER

The CHYAH05 is designed to allow the replacement of a factory radio with an aftermarket head-unit in select late model Chrysler, Dodge and Jeep vehicles. Provides a time saving professional head-unit installation while retaining full use of the factory amplifier and speaker system. The CHYAH05 is the perfect plug & Play solution when installing a aftermarket navigation radio.

Accessory 12V, parking brake, reverse, parking light and VSS output wires are supplied for full aftermarket radio OEM integration

Auto detects the presence of a factory amplifier, if present turns it on by the CANBUS commands triggered by remote input wire from aftermarket head-unit

Plug-n-Play installation into existing factory sound system provides greater time savings and does not harm factory vehicle wiring

You get the VSS signal from the canbus interface. That's the point of the peripheral interface, and the reason I upgraded from the Metra unit. The Metra merely turns on the factory amp. People are on here to help you if you ask nicely.

You also get the vss feed when you find the vss wire, and that's free...

I just had my AVIC N3 moved from to a 2007 Ram 1500 and am having the same problems with VSS, NAV Voice and ILLumination. Did you ever get the resolved???

You also get the vss feed when you find the vss wire, and that's free...

No one here wants to hear your sarcasm and attitude because you are too ignorant to hook it up at the radio harness. They gave you advice, tried to help you and you didn't take it so chill the fuck out.

The new Chrysler products use a CAN-BUS data exchange system throughout most of the vehicle's electronic systems. This includes VSS, tachometer info(in some places), accessory key position wake-up for things like the audio system, windows, A/C, lights, reverse sense from transmission, etc.. You might actually be able to find a pulsing wire that may mimic a VSS wire @ one of the wheel hubs, at the ABS sensor, BUT this may also disable the ABS, which may cause you and your family to die a horrible death in a flaming wreck because your brakes locked up and you slid off a cliff. You could also continue prodding around your vehicle's electrical system with a test meter (or worse, a test light), which is something Chrysler products already don't like, and eventually have your computer slip into a coma. You may also have one of the vehicles that completely freak out when the radio is removed, because the CAN-BUS line runs through them, and when the computer doesn't see any info on that line, it shuts off the electric oil pump. Fun. Or, you could just go ahead and buy the proper interface.

Man I have an 07 ram with a d3 and used the chyah05..... the only problem I had was with my reverse camera ....the thing thought it was in reverse all the time.

The chyah05 works fine, but, if the nav unit thinks it was in reverse all the time, check the polarity setting on your avic. Try switching it.

The Dodge 2007 RAM has VSS in 4 locations available to be used.

You don't need a CANBUS adapter to prevent CEL/SES or codes.

i drove my 2006 several days with nothing hooked to the Radio plug.

the Metra CANBUS only provides Ignition On/Off,

you can get that signal from the left cigarette lighter (which is also controlled by the DAP - Delayed Accessory Power)

so, in reality, IF you know how to PROPERLY poke around in your car and NOT destroy it as alluded to earlier,

you can just buy a regular adapter,

hit a VSS wire,

and hit the left cigarette lighter,

and you are good to go.

FWIW, Crutch field will sell you the Metra Adapter, or GIVE you the regular adapter.

the regular adapter ( or the Chayho ) would be better than the Metra, because the Metra has a large circuit board that must be slid somewhere.

Maybe you can get all the access to other needed connections....But why? The CanBus adaptor is idiot proof and doesn't hack into any factory wiring....

Just buy the adaptor. you DO get VSS, Power, Illumination dim, etc....ALL THROUGH the CanBus adaptor. Just get the correct one. There maybe like three different Chrysler adaptors. Just make sure yours is the CHY with 2006 CanBus.

Tom's right,

no matter how cheap you are, it will be much easier to back out the correct canbus adapter when you go to trade it in or whatever.

if anyone still needs the OEM Dodge wiring PDF's for the VSS, post up, and I will post them up
