New Bypass for AVIC Z2 (I Bought This Online..hope it helps)

[solrac]

Try which ever one you feel is best for you. These are the two that I have

found so far. I am still trying to find more if there are any. I would

suggest using the second one as it seems to me to be a better bypass.

 

This is the first bypass that we found. We will keep trying to find a better

one, but this does work if you follow these instructions correctly. Keep the

Parking brake wire grounded all the time. Put a switch on the GPS Antenna,

How? Tools u need is a solder gun, solder and splitters. Use a switch on GPS

Ant. It’s a coaxial Antenna (Power on the inside and Ground is the outside

shield) Put switch on the power shield wire. It’s in the center of the wire.

It works. When doing so, try not to break the out side shield of the wire

(make sure the outside layer of the coaxial antenna isn’t disturbed).Try it

When installing the unit. Plug up the GPS Antenna to the unit in order for

it to update your location, and then switch off the Antenna and drive. The

Only disadvantage about Bypass is that you must switch on the GPS Antenna

when u need the navigation. Unit doesn't take long to figure out were you

are at. 3 seconds at the most.

 

Here is the second bypass.

The only mod I have is a toggle switch on the e-brake.

 

1) Power the vehicle and unit with e-brake on and the vehicle in park.

2) hit the reset button on the lower left screen panel with a pen.

3) Let the unit reboot.

4) I have my unit to output to a rear monitor - I turn on the monitor and

see the front screen.

5) Start a DVD and let it play for a few minutes while still in park and

e-brake on.

6) Power off the car and turn the e-brake switch off.

7) Wait a few minutes before turning the car and unit back on.

8.) Start the car with e-brake off.

9) At no point should you see the message that the parking brake is properly

connected, if so repeat from #1.

10) I turn my rear monitor back on before driving again.

11) Start driving and start DVD where it left off.

12) Flip the e-brake switch while driving.

13) Enjoy full video and NAV functions that won't go out so far - I'm up to

150 miles on my vehicle and watched video for an hour.

14) Each time you start the vehicle follow from #8.

15) If you forget to start from #8 and startup/drive with the e-brake on it

will detect an improper e-brake connection. Once this happens, you have to

restart from #1.

 

This has yet to fail for me and my car states it's fully calibrated.

 

 

1. When I've reset the unit one time I also pushed the "restore to factory

settings" button, which reset all calibrations back to zero. However, for

the last now, 162.5 miles, I haven't reset or restored factory settings

without any problems.

 

2. Yes, I don't flip the e-brake until after I'm moving up past say 25 miles

or so. Until then, I have no use of extra nav or video functions. I will

flip the switch while stationed in park if I need to. That doesn't seem to

affect the unit detecting anything different.

 

3. Yes, my rear monitor is only connected to the Z2 through RCA cables. I

don't enable or disable anything on the Z2.

 

4. Once I'm moving with the e-brake on, I can fully watch video or perform

all NAV functions. I can flip through all menus, back and forth, switch

sources, or do whatever without any problems. The only thing is "right

after" you hit the reset button and are driving, while it initially

calibrates, the NAV isn't very accurate with the e-brake on, it will

"freeze" your current location, you can switch to dvd or audio, then back to

map and your current position is updated. Mine however, is accurate as I

drive now with the e-brake engaged.

 

Questions and answers from people who have tried this…

1. By E-brake switch do you mean you have it hooked up to the e-brake or

just a switch emulating the e-brake? Like a toggle switch...

2. Do we have to disconnect the VSS wire permanently and do we also

have to reset our z2 every time we start our cars if we want to watch DVD?

Answers

1. A toggle switch. One side to the light green parking brake wire, the

other to ground

2. Let me add in a quick reference note…

1. You have to use only an e-brake toggle

2. The VSS must be completely disconnected

3. You only need to reset the unit once with the e-brake on and vehicle

parked...but you must start the vehicle from then on with the e-brake off

and switch it on only after the unit is fully booted. If you get the

parking brake error, then start again from #1 and only turn the e-brake on

when video starts to play (initially no video) and moving >25mph to be

sure. After you turn on the switch, the video will pop on and all NAV will

work as long as the vehicle is running.

4. Once you turn the car off, turn the e-brake switch off and always start

the vehicle with it off.

5. If you ever get the parking brake error, you did something different or

wrong and will have to reset the unit and start back at #3. Otherwise, you

shouldn't ever have to reset the unit again.

6. The only nuisance is the flipping of the e-brake

Hey be nice

he spent money for this trying to help

I agree with mazdaspeed. Douche is a little harsh. solrac is just trying to share the wealth. Worse you can accuse him (or her) of is not keeping up with the Avic "culture". If people jump down on people for trying to share, even if it was possibly shared before, people will stop sharing.

 

solrac, thanks for the info. I don't know if it's anything really new, but it's interesting to see what people are selling on ebay. The worse part is that we all know yet another loser on ebay scammed a customer with some "worthless bypass". I know you might not think $5 is that much to lose for a chance to know the real bypass, but they are making a ton of money with nothing.

Disconnecting the VSS is a Hugh Deal Breaker for me.

 

I've tried my unit without the VSS and it was horrible, my location would skip around on the map and etc.

 

 

After connecting the VSS wire, wow, night and day difference for me! Very accurate and stable.

didnt mean no disrespect but we dont need another 20 pages on the same thing that we already have it only clogs up the site with redundancy.like i said im sorry for offending you .
