Good afternoon all, I have removed the GPS/Navigator cradle from my 18 GSA as I’m using a phone and quad lock for nav purposes. I would like to utilise the now spare electrical feed. Does anyone know what amps this feed puts out, is it a constant live or only live when the ignition is on? I’m thinking of running another DIN outlet off it to provide further gadget charging capacity.
Thanks in advance for any replies.
 
I don’t know about the output, but my navigator asks if I want to power it off after I turn off the ignition, so I believe it is switched to come on with the ignition and go off when you turn the key off or press the power button for those with keyless bikes.

Cheers, I’ve got a mate coming over with his fluke tomorrow to check the voltage. I looked on the net for a copy of the wiring diagram and it showed there’s an inline fuse. If I can trace it, I’ll get an idea of what amps it’s rated for.
 
I have done precisely what you want to do, and it works fine. I used a connector from Nippy Normans to connect this outlet to a 12V socket which I used to house a 12V to USB adaptor which provides the PD type fast charging used by my phone. I made a bracket which holds the 12V socket under the DIN accessory socket.

I don't know the current rating, but believe it is probably 5A which is more than enough. I doubt there is a fuse as I think this and the DIN outlet are managed by the bike's electronics and just shut down if the max load is exceeded.

I found this was better than my original method of tapping into the feed to the DIN socket because that did not shutdown when the ignition was off. With the phone unplugged from the charger the charger stayed live indefinitely, probably due to the residual current drain of the USB converter, and this would eventually flatten the bike's battery.

This did not happen when using the satnav power source, and this shut down fully after a short delay when the ignition was switched off.

They say that great minds think alike. Does NN have the requisite connector to join the power outlet to the sat nav power source? I was planning to snip it off the cradle. My plan is to have a separate power source to recharge drone batteries primarily but it’s good to have an alternative power outlet.
Many thanks.
 
I’ve just seen this on NN’s website. It looks like what I need but, it had this feedback:

“Fits the lead provided by BMW, easy to use, just be aware it goes live when switched on but does not switch off when ignition is shut down”.

Why would the original wiring to the cradle lose power when the ignition is off but not when this extension is added, it’s not a device that can bypass the relay originally fitted (somewhere in the management system presumably). The description provided by NN says “ Your GPS will now be powered up and off with the ignition with no risk of battery drainage!”. Who is right?

Further to this discussion. It appears that out of the three wires coming from the NN connector, only two are required. You need to work out which provides power, which provides earth and which is the red herring. The red herring provides a 12v feed that goes off when the ignition is on and so is of no value in this situation. The item below however, seems to take the faff out of trying to find the red herring and provides simply live and earth. The description says it can be used in the CAN Bus system but doesn’t specify if it will fit the outlet that once provided power to the Navigator cradle. Any thoughts?

The wires are numbered.

No.2 is the red herring.

No.1 is +ive

#3 is earth then? Is that indicated in the instructions or you just need to work it out. NN advises that the live feed, as far as they’re concerned, ceases after 15 min to protect the battery. Can anyone confirm this.

Sorry, 15 min after the ignition is switched off.

Marco of Toutech confirms that their plug is for the outlet left by the Navigator feed. Lip curlingly expensive mind.
 
Not really much more than the NN one.
Best way is to go to the BMW CAR parts though as the same leads are available for a lot less money.
Not sure if anyone has come up with the part number for the female one needed to use the Nav on another bike as yet?

£27 with PnP :eek:. The lead only looks about 6 inch as well. I’ve ordered one anyway and I’ll solder an extension on it. :thumb
 
This is one I used: https://www.nippynormans.com/f650gs...any-garmin-or-tomtom-gps-into-the-bmw-harness

Very expensive at £19, but convenient to have one with the three wires already in place ready to connect to my two pin connector.

In my experience it definitely turned off with the ignition though only after a delay.

The wires on the NN connector have the numbers 1,2 and 3 printed on them, though they are quite hard to read. I've taken the insulation tape off the cable I made to show you how it is connected. In the picture below the red cable is 12V, black cable is 0V and the unconnected one is the unused data connection which normally allows the NAV to access bike data.

Looks good. I wonder why NN left the unusable data lead in place? I plan to do the same thing when the Touratech lead arrives, the beauty of. That one is, there’s no third strand looking for somewhere to hide. I may buy some more suitable (read less expensive) waterproof connectors and fit female ends on to various applications then I can change to whatever is required.

I use those waterproof connectors on most things and as you say, you can then make different accessories swappable onto different power sources. I also have the HexeZcan and it comes with the same style of connector, though I think the Denali version uses three way connectors. I used to buy these connectors as kits and fitted the pins myself, but it is a bit fiddly, and I now buy them ready made with wiring tails already fitted which makes life a lot easier. I just have to ensure that the red and black cable positions are consistent with the ones I have already used when I replenish my stocks, as they do seem to vary!

Yes , No.3 is earth.
 
Not surprisingly, I found the BMW OEM part is available posted for less than Nippy's TT part. Just have a look on eBay, there's a couple of BMW dealers with parts like this. I bought the SatNav blanking plate for me new-to-me R1200R from Ocean Motorrad on eBay.
 
Nippys is £20

A main dealer is anywhere between £9 -£15

the trouble is people buy em from nippys and then get the hump trying to recoup there losses when they sell them

When people tell them they can buy them cheaper OEM
