Garmin/DIN plug?
G`day all, my GPS has a poxy cigarette lighter plug that is next to useless on anything rough, I brought a DIN plug for it, but with the circuit board in the Garmin plug it will be a bit of a messy conversion combining the two, what is the common mod for providing constant power.

Hello Col,
Which Garmin? The ones I know use unregulated power supply from the 12v socket. Read the instruction manual. If it mentions supply voltage between 12 and 40V, it's a straight plug replacement job. ------------------ Roman (UK) www.overlandcruiser.info |

Roman this is my plug, it has the voltage regulator in it, I was just on the GPSWarehouse site and saw the other type plugs you were talking about, looks like I got a model that requires external voltage regulation. http://www.horizonsunlimited.com/ubb/frown.gif Col |
My Garmin (GPS V) came with a cig lighter and a round 4 pin plug (at the GPS end), i just cut off the cig plug and hard wired it into my dash (onto a permanent live... think it was the stereo memory feed, so it's got a 5a fuse in the fusebox already)
that way, when/if my GPS batteries are flat, the GPS doesn't turn off whenever i turn off the ignition. I've heard of a 3 way plug/lead assembly, which consists of 1) cig plug 2) GPS plug and 3) a PC data plug... anyone heard of these? mine also came with a PC lead, but it doesn't allow external power for the GPS through it! (and only 3 of the 4 pins are used on the GPS plug... handy eh? same with the cig power plug, it uses two pins, but as the plug is all moulded you can't get into the darn thing!) |
Jim I just had a look at the V plug and its similar to the one Roman mentioned, your GPS must be internally regulated. My plug is also a 3 way plug, power/PC/12v. The stupid thing is the PC can`t power the GPS, only the AAs or 12v will.

Hello Col,
OK. This is a 3V power supply. The easiest way to go is to disassmble the OEM plug, solder a piece of 2 way cable to the metal parts inside the plug (one for the centre pin (positive) and one for the outside contacts (negative). Then, put a piece of appropriate size thermal shrink tube over the end to isolate the exposed parts and attach a DIN plug to the other end of the cable (observing polarity). Not an elegant way, but it works. Another option - depending on your engineering skills - is to build a very simple regulated 3V power supply housed in its own box - just for powering the GPS unit. The advantage - the PS it can be properly filtered so that the GPS electronics will be protected from voltage spikes. ------------------ Roman (UK) www.overlandcruiser.info |
Roman your`ve got me thinking now, there are some cheap cables on ebay which I can mod, I have also just found a 12/3v regulator which I could also hard wire or DIN plug in.

Col,
Another dedicated power supply: go to www.rswww.com , then search for item 361-4804 . It requires replacing the cig plug at one end with a DIN plug and wiring the Garmin plug to the output cable. If you want to build your own PS (e.g housed behind the dashboad), check item 466-7045 or similar. ------------------ Roman (UK) www.overlandcruiser.info [This message has been edited by Roman (edited 22 November 2004).] [This message has been edited by Roman (edited 22 November 2004).] |
Roman, thanks mate, I think I prefer the first option, easier and cheaper, and it give`s me the option of other votages if required.
Building my own with a power supply would be neater, but I think I`ll go the ready made option, thanks again for the link. Col |
Roman I ended up going with the first option, I disected the origional plug and the din, soldered the wires and joined the two halves, it was the cheapest and easiest way and the end result does`nt look to bad either, thanks for your input.
