76CSx 12 volt supply

| Is there a low cost way to connect the unit to an external battery? The $30
for a cigarette lighter adapter seems high.

Gilsson (GPSGeek.com) usually has pretty good prices on cables and
other accessories for Garmins. AIRC, the 'x' models can be powered
through the USB connection and there are lots of inexpensive generic
cigarette lighter to 5V USB cords.

Cables and connectors for most Garmin models.

| Good thought. I will keep the USB option in mind.

| Ebay is a good source that is where I get mine.

I bought a Garmin 12-Volt Adapter Cable, part number 010-10085-00. It
has the round four pin plug that has been used on a number of Garmin GPS
receivers over the years.
When I got it (it was the first one I've had or seen) I was a little
surprised in that it did not appear to have a DC-DC adapter built into
it. It is simply a fused DC plug and a cable that takes the nominal
12VDC automotive source and connects it to the GPS.
I tested it with a VOM and it sends the source voltage straight through.
Being used to Magellans that required a 5 VDC supply I was a little
nervous about connecting this to my shiny new 76Cx. But the Garmin web
site listed that cable as an accessory for the 76Cx so I tried it and it
worked fine.
That cable can be used with the GPS 12CX, 12XL, 12Map, II, III, III+, V,
60, 72/76, GPSMAP 60/60C/60CS (and 60 "x" models), GPSMAP
76/76S/76C/76CS (and 76 "x" models), and GPSMAP 176C. But it is *NOT*
for use with the GPS 12.
I bought my adapter on eBay for $6.99 plus your typical $12 rip off
shipping fee but I figured that was about half price. Had I know then
what I know now, I would have bought the connector here:
http://www.gomadic.com/accessories-...ugs-garmin.html
and made up my own cable. And I probably would have also included the
serial TXD/RXD pair in the cable just in case I ever wanted to use it.
The Garmin specs on the 76Cx do not say what the maximum input voltage
is on the power connector, my bench power supply puts out 13.7 VDC no
load, most cars have a similar voltage on their DC outlets when the
engine is running and the charging voltage is present. So you can use a
nominal 12 Volt source but I be careful with anything over 14V. I don't
know that the GPS receivers will handle the voltage on the 24 Volt
systems found in some vehicles, boats, and RVs.

Some of the earlier Garmins did not have any internal regulation
and were very limited re input voltage. I still have an expensive
Garmin cable for some model with regulation built into the cable
(don't recall which old model, long since gone).

Wouldn't save much over GPSGeek's price for their cables. Just the
connector is $3 plus $5 shipping and you'd still have to get the 12V
lighter plug whereas the GPSGeek eBay price is $8 plus $5 shipping for
their cable ($10 + $5 if you want both power and RS232 connections).

The Garmin specification for the units you listed above that use the
4-pin round connector is for input voltages from 12 VDC to 36 VDC (see
pg. 91 of the 76CSx manual) so there's no problem with using 24 V
systems.
The GPS 12 and 38 use a similar connector but with an additional
plastic pin in the middle so the cables can't accidentally be
interchanged. Those units require an input voltage of 5 VDC to 8 VDC
so their cables include a voltage regulator in the cable.

Thanks for the lead on that. Sometimes I get stuck in doing the more
expensive hard way because it was a cheaper way at some point in the past.

Thanks for the details on that too. I looked in the manual but didn't
spend enough time reading those two pages. One says up to 36 Volts and
the other says 10-32 Volts.
