Got the 378. Knew the internal battery was toast, but unit worked fine.
Replaced the little battery, now it won't boot. Went back in, checked that polarity was right, and connection was good on the board.
The ribbon connector from the power connector in case to board is good, and getting power to the board.
Fuck. Think I have a three hundred dollar brick.
It has been a few years since I did a board battery, By chance can you put the ribbon connection on the wrong way ?
I took a lot of pictures the last time I did it and will dig them up and look for any ideas.
It looks like you cannot do, what I thought you might have done.
Perhaps wrong area to pose question. Purchased CN North America 2013.1 via disc and loaded on Mac and Base Camp installed, etc. Previously had CN on my PC but thought I would go with the Mac as the PC is old and slow, as is its owner. All loaded fine but when I tried to load updated maps to GPS got the previously reported error messages, not enough space-unit not compatitable for updates, etc. Saw a post about de-selecting CN on the GPS did that still no go. Contacted Garmin, not much help. Read that there is a post somewhere about the proceedure for updating or how toupdate the 478 through Base Camp-Mac but cannot locate it. Does anybody have a link to this post or suggestions on how to update the 478. Have a 512 datacard but will not hold all the info I need. Thanks
I had the same issue, loved that the 478 held the entire map on internal memory. I bought the lifetime map update card, ran through the process, oh snap, it won't fit. Called Garmin, took a while but got routed to someone who could help, needed the 512 external card, they sold it to me at a big discount and then helped me load partial maps on the internal memory and the remaining on the 512 external card. It was a while ago, I don't think I could do the ENTIRE US but between internal and external card got pretty darn close.
My advice is to call Garmin back and push for help, my call got routed a few times.
Thanks MT. I need to call and push. Had a problem before and got hold of somebody that could actually address the problem. K
The new maps have simply outgrown the internal memory in size. The data they now contain is huge. But you can still fit a lot and reload what portion of the US you want, when you want.
You use the Garmin "Map Updater" program for the 478.

And this here may be the single biggest reason to buy one of the new GPS models.
Let us know how you did it. I'm thinking of upgrading maps, but am concerned about the installation procedure.
I know several guys who have reverted back to the 478 type unit from the new units. Garmin has not made an equal to it yet.
But it's a personal choice of course.

What's the going price on the 478s right now? I have a NEW factory refurbished 478 (unused other than I immediately added a screen protector when I received from Garmin). New OEM battery. Just the unit/battery. No memory card or cables. Obviously has builtin maps.
I have a 276c+ and was keeping the 478 as a backup but I've been thinking of selling it, I keep figuring eventually Garmin will release something more modern that I actually like
There's this one up for sale in the flea market at the moment:
I was able to load all of city nav 2013.3 to my 378 but you'll loose all of the marine maps.
I've got a 478 that I bought used off of craigslist. The thing works great when its plugged in at home, but if its plugged into a car or the motorcycle, it cuts off every few miles. I've even used the exact same AC adapter in my truck and it still cuts off. The cable on the motorcycle is brand new and even that cuts off. The battery is charged so it looks like it would just switch to battery power but it doesnt.
Edit - One other caveat, when you turn the power off on the bike, it goes back to battery power?!
My concern is, I want to send it to Garmin and just pay the $170 for service but I have had the unit open to check the cables and try to make sure it wasnt just a loose connection. Its not under warranty so I guess that shouldnt matter.
The other thing, with the unit being so old will they even attempt to repair it or just take my $170 and tell me I need a new unit?
I had one of mine (478) replaced with a refurbished unit last month. No trouble with transferring my Lifetime maps, no issues with registering the new unit with myGarmin.
AFAIK, Garmin policy is to replace the unit with a refurb and then repair the faulty unit to new spec. At that point it becomes part of the replacement inventory. In the case of the 276c, this continued until Garmin ran out of parts.
I'll probably have my second unit done this winter.
Thats great to know! I did notice on the list of repair rates the 276c says not supported while the 478 says $170. If $170 gets me a factory refurb'd unit, I'm all in.
That would happen on my 478 also. Seems that intermittent losses of power (from the bike's wiring? from a loose / failing battery?) would shut the unit down.
I took care of it with software. I selected the "don't shut off if power is disconnected" option somewhere in the system menu.
All good now.
Mine is already on that setting. And it fails on the bike wiring, the cigarette plug, and even the AC plug in a vehicle (my Jeep has an AC outlet) - All three are different harnesses. The crazy thing is when you plug it in indoors - with the same AC plug - and shake the shit out of it, it wont fail.
Does it just wink off?
Probably a vibration issue that you can't replicate by just shaking it.
You're probably right. Its on... and then its off. No warning or anything.
