Hi All,

I've been considering power options for iPhone / satnav etc. and as I typically use my phone in a Biologic case a USB outlet from Nippy Norman connected into the GPS lead under the headstock seems a good plan.

Is this as simple as it sounds? I did read a few posts about iPhones not charging on a GS??? Its an iPhone 4S.

Cheers,

John

you are unlikely to bust the Canbus amps limit but there are reams of posts on here about gps or phone cradles staying live even when the unit is removed and draining the bikes battery, cannot recall the detail but I think some model years suffered and some did not

if you are certain whatever you leave on the bike wont pull any juice you should be safe
 
Is it as simple as it sounds? Yes

Will it work? It should do. It's easy to find out, just wire it in and see if the thing charges. It won't blow up.

IPhone not charging has nothing to do with it being a GS, it's to do with what USB socket you use.
USB have four leads - two used for power and two used for data. A USB socket for charging might only have the two power leads connected, but iPhones won't charge from these as they need to see certain signals on the data leads. Some USB sockets are made with this in mind and some are not. Need to try and see.

On my bike I have a "normal" 12v car socket wired to the gps power lead with a USB cigar lighter charger in it.

Have found this to be a problem with my Samsung smartphone. And haven't found a solution yet. Other than to buy a spare battery which is a short term solution.
 
The problem can also be with the USB lead.

One fleabay lead I have won't charge my samsung galaxy SIII but the other marked as fully wired does.

I use a relay to switch a cigarette lighter socket on, plugged into that is a 2 amp USB adaptor from halfords, Works a treat once I got the new USB lead.

I believe Apple stick a chip in the cable for authentication reasons (especially if the latest IOS is used), some ebay leads won't work as they don't have this. Try using a genuine Apple lead
 
I have a BMW socket (is it din?) to cigar socket cable. I presume plugging an Apple USB charger into that must work from the accessory socket?
 
Just wire direct to the battery to avoid CanBus issues. Get a cigarette lighter thing from Maplin, and plug a USB charger into it. Or just a USB socket thing that takes a 12V feed. Regardless, make sure that the USB Socket can deliver at least 1A @ 5V or ideally 2A; many phones take up to 2A these days.

When you are wiring to the battery, electrics is electrics. Period.
 
I think the trick with some devices charging from USB is to connect the two signal pins together (not the power ones obvs) behind the socket. Many tablets etc require 2 Amps. Remember, USB is five Volts.

The sat-nav power socket at the headstock gets de-powered if the bike thinks nothing is connected to it. I was using it to power my Garmin but I've given up on that now.

Easier said than done. And I have tried the USB charging cable only and that doesn't work either.
 
Sounds like wiring the USB socket directly to the battery is the best option. Could you switch the supply through a 12V relay fed from the standard DIN socket under the seat? I'd like the socket to shut down when I turn the ignition off. I'm guessing that the relay might cause problems with the canbus system???
 
See switched power the easy way sticky.

Your worries are groundless.

Wire it directly to the underseat aux socket or any other live feed controlled by the ignition switch, the rear light ( not the brake light) feed for example. It's a phone charger, you will not need a relay.
 
Get a usb that has 2amp charging. B and q do one with both a 1 and a 2 amp slot on same usb insert. 4 squid. Works on my samsung galaxy
 
I see what you did there...... Clever :)

I'm a real live wire sometimes :D

To the OP....

There are lots of 'How to do it' threads on UKGSer (including the better ones in the sticky section) and many thousands more on Google. Better still, there are lots videos on UBoob showing how to do all sorts of things on or to a motorcycle, some are even quite good.

Google something like: 'Adding a GPS to a motorcycle' or 'adding a phone to a motorcycle' and then select Video.

Browse through the many that will pop up, you are bound to find one you like and / or shows near enough what it is you are trying to do. Copy the method shown and the job's as good as done.

It's a safe bet that any question you type into UKGSer will have been asked by someone and answered by someone else at least once before somewhere in the world in the deep mine of information that is Google. It takes less words doing a Google search than it does asking UKGser in that you don't gave to give a lengthy (and often confusing) explanation of what it is you are trying to do. Google is quite good at working out that if you enter just four words, say: 'adding GPS to motorcycle' into the search bar, you are probably not looking for detailed instructions on how to milk a cow.

For example, plucked at random:

Not to be confused with:

<iframe width="560" height="315" src="//www.youtube.com/embed/ziITe09ahUs" frameborder="0" allowfullscreen></iframe>


Now, I didn't need to go to UKfarmers.com's doubtless excellent forum to find out how to milk a cow, adding in all sorts of explanations that I was new to the dairy industry, was hoping to enliven my cornflakes or any such old tosh. I just asked Google to find me something that might help me, very easily. Of course you can still ask a question of UKGSer but sometimes it's fun (and easier) to do it via a Google search. OK it takes a little bit of time and a bit of imagination but the rewards are often greater than the sum of its parts.

What is sometimes fun (and above all helpful) is to do the search, find what it is you want to do on Google and do it.... Then start a thread on UKGSer saying something like: How to fit a phone connection, add a bit of explanation on what it is you did (bods love pictures, never forget that) and add a link to anything you found helpful. People will think you are a god :bow trust me.

PS Don't get hung up that your 1200 has a Canbus as opposed to a conventional fuse box. In reality, the Canbus is much simpler as, more often than not, you can just add simple peripherals (like phones and GPS) to it, just like tying one piece of string to another. Just think of it as having a fuse box burried away somewhere in a box, with a convenient (ready fused) live wire coming out of it, ready to use. Want to be really safe and use a ready switched supply? That's easy. Use the live feed that runs to the aux socket. That way, if it does trip out, the worse that will happen is that the aux socket won't work. Cure the problem and the system will re-set itself (all in that hidden away fuse box) and all will be well again. You only need a relay if you are adding things that will draw a reasonable amount of current (like lights, heated grips or maybe a horn) in short anything that will draw over 5 amps which is the bike's general limit. A phone or GPS charger will be a fraction of that. How many amps is perfieral ABC? The instruction book will tell you, or Google probably will. Still no good? OK, How to work out amps? It's easy... amps times volts = watts. Most electrical items will have their wattage info available written up somewhere. Your bike is near enough always 12 volts, so you can do the sums from there.

PPS If you have an iPad or iPhone, it's sometimes useful to download a UBoob clip to it, to take into the garage whilst you tinker away. The problem comes if you do not have a reliable wifi connection in your man cave. Never fear, there is an excellent app that will allow you to store UBoob clips. It is either free (adverts that can be a little annoying) or a couple of quid for the 'Pro' version....

How? Ask Google something like, um, er, let's see what happens if I ask it for, what is it that I am try to do? Ah yes........ 'Add UTube to iPad'...... of course it is... et's see what happens if I type those four words in... Dum dee dum dee dah.... Oh there are lots of possible answers...... Scroll down a bit.... This looks promising....

And go from there.

There are doubtless other ways (Google had loads) but it worked for me. I have not got the faintest idea about downloading software, fiddling about in iTunes or any such IT lite malarkey. But I needed to get a UBoob clip onto my iPad to show to a bod in a pub, without a wifi link. I guessed that it should be possible and, if it was, someone somewhere from London to Sydney to a hut in the Central African Republic would have done it and would tell me how. Four words and thirty seconds later I had the answer. It's a thing of genius.
 
... It's a thing of genius.

I'd go further than that. Its a thing started by two genii that now employs a good many thousands of very clever people and over half of all the worlds computers. It is a thing of joy and wonder. Future generations will look back upon these times with envy and misty eyes. As they bend their backs in servitude to their new machine overlords!
