NICE!!!!!!!!!!!!!! ty so much for posting this and it better get a sticky of some sort!

yes, remote start diagram would be so awesome also!

 

[Chrish051873]

definitely a sticky worthy post, thanks and good job Justin

 

[sonic007]

Not a problem! Been a long time coming just kept forgetting. Not sure how to add pdf files to the page. Any suggestions?

 

[Chrish051873]

depending on file size.

attach it, zip it

 

[sonic007]

Ok updated it. Just converted it to jpeg.

 

[Trevork08]

Would anyone be able to help me figure out which wire is the positive and negative on the speakers? I'm a little confused with this top post and which is which. Thanks.

 

[sonic007]

The first color is positive, the second negative. All speaker wires with stripes are negative.

 

[Evict]

Wow very nice, exactly what I was looking for!

So is the wiring on the mylink HU the same as the non-mylink? Don't want to bother buying the AA-GM44 if it's not.

 

[sonic007]

It should be. Ill double check today.

 

[DjeepMyers]

Would interrupting one of those Can-Bus wires disable the in motion I mobilizer on the mylink? Reason for asking, when on a long drive and destination changes, my gf in the passenger seat tries to update the destination in the BringGo Navigation but the address input is greyed out unless I am going under 4mph. If one of those wires is the solution, how would I go about fixing my issue? I'm sure clipping the wire would cause other issues.

 

[sonic007]

I would never inturrupt a Can-Bus wire. It does alot more than people think.

 

[DjeepMyers]

Do you know how to fix my issue? Do you by chance have the schematic available for the mylink radio in a 2013 sonic LT hatch? If the mylink receives a signal from the VSS interrupting that should allow my gf to alter out destination I would imagine? Also I am aware that doing so would disable the auto volume adjust at higher speeds but I'm willing to give that up.

 

[sonic007]

Interrupting it wouldnt help. You would have to apply the correct ammount of ac voltage. In the newer vehicles all that info is done through multiplex data wires. Vss, parking brake, reverse signal, etc. It may work through the GPS antenna like some of the newer pioneers. You have to change the software to bypass it. As far as I know theres no way to bypass it in the mylink. I can see if I can find a schematic though.

Not sure if GM uses a different can bus than I'm use to. All can bus I've seen is a digital signal not AC. Also cutting 1 of the can bus wires will only cause a can bus error code. Everything should still work as intended since can hi and can low are the same redundant data only opposite voltages

 

[sonic007]

Right sorry i didnt explain further. The data bus isnt ac. Typically the vss signal is ac. I didnt break it apart. Lol

 

[DjeepMyers]

Yeah a schematic would be great of you can find one thanks

 

[DjeepMyers]

Any luck on a wiring diagram for the mylink? I ve been googling and only coming up with a $300 GM Service manual. $300 is too steep for me. Maybe of it was like $100 I would bite the bullet. And my mechanics AllData system only has up to 2012 models.

 

[sonic007]

Mine does too. Ill have to keep digging.
