Permanent live feed to GPS mount for Carpuride screen

[Peter Lawson]

Hi there, I want to wire my BMW satnav prep cradle with a permanent live so I can run a Carpuride screen WITHOUT the BMW GS 1250 canbus dropping the voltage on startup. Therefore I need (I think) a white female plug to connect to the Factory Repair Cable (BMW 83-30-0-413-585) plug connected to a female USB connector on a short wire as an adaptor so I can then plug a Quadlock waterproof 12v to USB smart adaptor in here. Does this make sense? Any help appreciated, many thanks Peter

Won’t work and you will blow it up. You’re going 12v to 5v and then back to 12v.
Absolutely no need for the usb in that configuration.
Quadlock directly to battery or the “smart” part is a waste of money.
Maybe RTFM on the Carpuride and/or Quadlock

I would say direct to battery (always a risk of killing your battery so the bike won't start), or a neat solution like a PDM 60 (or a Healtech Thunderbox)

Thanks - the problem is that the Carpuride does not have a battery and the canbus drops the voltage to the standard satnav prep on bike start up. BMW dealer says that there is no way to program this out and standard satnavs have a battery so it’s not an issue for them… I’ve even asked Carpuride if there are plans to put a battery in their product - and they say not…

Satnav prep is 12v. For the small amount of time it takes the unit to reboot - save the £ and aggro of the Quadlock.
We have several of them on bikes and ONLY use them on the enduros. The GS batteries sit above the cutoff threshold of them so you get a dead battery if you don’t turn them off.

I have the same issue, day to day its ok, but when away touring, stopping and starting the bike having to wait for the nav system to come back alive is a pain (especially say in a unknown hot city where you want to turn bike off while stood in traffic and then restart when traffic starts rolling, but then you have no sat nav for the next 20 seconds or so). I wondered if there was an option to wire some kind of capacitor?? or energy storage device that would keep the volatge up during the momentary cranking of the engine when the 12v factory sat nav plug looses power for a second or so?

Do you have an optimate or similar fly lead on your battery?
I occasionally fit a Satnav to my XJR, I connect the power lead from the Nav to the optimate lead. When parked up I just unplug it so no chance of battery drain.

That’s what we do with the Quadlock “smart” charger. It isn’t very so either unplug it or have it somewhere visible and use the physical switch it has.

Yup, bought one of these thankyou - I was trying to see whether I could reuse the GPS prep wiring rather running anew…

Exactly, hence my asking Carpuride if they were considering putting a battery in their devices…

Fit a Healtech thunder box ( 16A version ) and instead of connecting it directly to the battery connect it to something like this - ?
