Re: T31 Series 5 Nissan Connect
So I can finally comment on using the factory around view monitor with an aftermarket head unit. I finished my audio install this week and I am 99% happy. I installed a pioneer AVIC Nav unit from my previous car along with speaker upgrade, amp and sub install. I was also able to retain steering controls with an Axxess universal steering wheel controller. I will post more details later but now for the around view monitor.
To answer the question "can you retain your around view monitor with aftermarket head unit?"
Well yes and no.
Here is what I have found
The AVM module sends a composite image to the headunit via factory loom so this was easy to splice into an RCA for the aftermarket unit.
The problem lies in the camera AVM positive trigger. The factory loom uses 2 triggers one is a 12 volt which is only activated when the gear is placed in reverse. The other trigger is 6 volt or closer to 5.5 volt which is activated when the camera select button is pushed. The pioneer, and most aftermarket units for that matter require a 12 volt feed to activate the camera input.
If you just want the camera to switch on in reverse, no problems, just use the 12 volt feed, you can even cycle views using the camera select button, however the gear must be in reverse. the 12 volt does not trigger if you just push the camera select button and cycle through views. So therefore you loose the ability to just use the camera view cycle without being in reverse and also loos the ability to see the forward camera.
I tried using a relay and also a transistor setup using the 5.5 volt feed as a trigger to activate a 12 volt feed for the headunit but it just would not trip the relay or activate the transistor.
I did manage a work around, I have installed a separate switch, in one of the blank spaces near the vehicle stability control switch, which switches a 12 volt signal to the aftermarket unit tricking it into thinking that the factory 12 volt trigger is on. You can then place it in reverse or just cycle through the camera views using the camera button regardless of gear lever position. Once done you just turn the switch off.
This is not ideal as it requires another switch to be pressed to use the cameras but it is worth it to retain the around view monitor. I have found the side camera so useful when parking in the garage to avoid storage items on the floor.
Hopefully down the track someone figures out a way to up regulate the 5.5 volt feed to 12 volt and teh switch will no longer be needed.
I know that post was a little confusing but it proves that the AVM can be retained with an aftermarket headunit

Re: T31 Series 5 Nissan Connect System (including Navigation)
OK so I have been stomping around in the Series 3 and 4 forum about map upgrades and just getting confused. Now Jalal has pointed me in the right direction I'll start again...
Can anyone who has been there tell me what map version would be on my T31 Series V TL Nissan Connect Audio and Nav system? Is it written on the SD card? THe manual says upgrades are only possible thru a dealer. Is this correct? Are there any upgrades even available?
T31 TL Auto Series V, Phantom Black, ECB nudge, Integra steps, Nissan tow, Boot liner, Rear spoiler, Tints, Side mouldings, Scuff plates, Out of date Maps, Oil on the Air filter.
