I need some help ===== I created a map useing MapEdit + cGPSmapper --- uploaded
it to my Garmin Streetpilot 2720 with Sendmap but the map only displays for a
second or 2 and then disappears ---- have I done something wrong.
Any assistance would be great.

What version of firmware is installed in the unit? I ask this because our Garmin users forum has had problems with the latest versions of firmware - when you...
OK, this might be a long shot, but let's put these things together. - A member on another forum has found that the units die when the voltage drops below 7.6V...
Modern electronics normally use an electronic switching regulator to control the internal voltage. So if you are going to measure current drain it is ...
size of wire for the tiny amount of current used here will make very little diff. i would suspect the unit actually works on 7.5VDC. and as pointed out you...
Disagree times 10. The current carrying capacity of wire is directly related to the outside surface area, not the inner volume. Current is a surface...
Total bull Who taught you electronics! Mike ... From: map_authors@yahoogroups.com [mailto:map_authors@yahoogroups.com] On Behalf Of MARK NEWBY Sent: 12 July...
That is correct, I meant voltage - something you can vary over the range of test parameters. Don't listen to what I write, listen to what I mean. I do not...
Mark, There is a minor problem with your battery life calculations: Ampere-hours do not add when you connect the batteries in series, you just have a higher ...
Hi Bertho, I am not perfect - but all my equipment works in the field when I need it. I spend a lot of time with sealants, machine vibration proof mounts, and...
Good getting a bit more info now. Have you considered something as simple as rust or oxidisation of the socket involved? A dose of switch cleaner might solve...
My lighter plugs have never had the cigarette lighter installed. I took it out when I bought the truck and threw it in the glove box. If they are used as a...
You are talking complete rubbish, as you appear to often do. Go back to school, and learn about ohm's law, and resistivity. Current _does_ flow on the inside...
Thank you for the kind and courteous reply. Nonetheless, this will turn out to be the answer to the issue. It is critical to simplify the issues. Not...
i think the issue here is one of firmware and how it monitors the sensors of theprocessor. there is only one way to fix this and thats to get the garmin geeks...
I think we are on the right track - the interaction of these parts. Garmin is not going to fix it because they probably do not think it is broken. There is...
So you do not think that I may have done something wrong when I created the map and it's properties ----- I had a simular problem once before and after playing...
I do not believe at this time that the display dying out is a firmware issue. I reserve the right to change my opinion if new information comes to light....
You p'haps might be on the right track [pun] but it will still be a firmware issue, I would also get clear upon what you are putting it down too. I doubt very...
The firmware tie-in is because the battery type is selectable. I assume this engages a different monitoring circuit when you change the selection. As I said,...
Good post as always at least your thinking along the right lines. The problem is, esp with multiple cells, and such low drain current, it is very diff to...
Has anyone seen inside a GPS? When I opened my 60CX when I had problems with the unit fading away with a new set of batteries I found that there is no ...
I think we know one thing for sure: When the current drain causes the voltage to go below a certain level, the unit shuts off, probably due to the internal...
How about planned obsolescence by manufacturers? From: map_authors@yahoogroups.com [mailto:map_authors@yahoogroups.com] On Behalf Of MARK NEWBY Sent: Monday,...
I like your critical thinking - but this does not have the feel of planned obsolescence. These units appear to be designed to meet a price/profit margin, and...
... Not really to do with battery power curves. Battery power curves are real, they do vary a lot by the metals involved, and understanding which type of cell...
This has realy gone in the wrong direction ----- just the map data that I have added disapears after briefly showing on the GPS screen, the background map is...
