Default New hds 7 wont pick up gps signal ???

First off its not in the boat. I just got it and hooked it up to a ac-dc converter. Powers up fine but will not get a fix on me - Is it that sensitive that it cant grab a signal next to an open door ? I only live a few miles from ocean and it has usa insight loaded in it. I'm not sure if this is the right unit for me ....so many gps/chartplotters out there and they all seem to have issues. I want to be able to plot a course etc -safely and find fish - isnt there one that does both with no issues ???? I was going to get a 740 s by garmin - in a few weeks they'll have that new raymarine out - but who knows its probably junk.


Thanks E

The internal antenna will not pick up inside a house. It is the overhead aspect that requires at least 3 satellites to lock in before it can give you a fix. I have hooked mine up inside as well, no GPS and did not expect one. My Garmin Nuvi for my truck does the same thing.

Captain Frosty, if I leave mine on for about ten minutes it will eventually get the satellites indoors. It is a one story with foam insulation in the attic. But as you can barely see it is off by quite a bit.

I eventually got one as well -toyed around with it a bit. Setting up routes seemed very slow and tedious. These cant set a course for you like a car ? point a to point b and guide you a safe route ? I know the garmin 740 s does it for you with a push of a button .....Maybe its not a big deal - dragging the cursor around trying to find ways around obstructions seemed like a pain in the butt - and the more I read on here - guys are having issues with the update etc ..... This thing may be headed back to the store for something else ....

I don't know what that Garmin will do but no it will not map a safe route for you. You must create waypoints and create your route between them.

The new garmins WILL plot a safe route for you (just enter your destination.) Saw the demo at west marine.

My hds 10 picks up the sattellites inside my house 6' from a window under a porch. Sometimes I wish it wasnt so sensitive when I am working with it indoors as it then recenters the cursor 100s of miles from where I was entering data.

To use the 'Guide To' feature you must also purchase the Garmin 'BlueChart g2 Vision Card. Concern is just how 'updated' are these cards, and how accurate is their tidal info.. Not sure I want to trust a chart card for 'automatic safe passage charting'. Nice idea, just not sure how SAFE it really is.

And yes, my HDS also gets great satellite reception inside my house, on the couch, in front of my fireplace. My wife wishes it wouldn't!

You would have to be crazy to rely on ANY marine GPS to take you on a safe course. I don't care what Garmin says it can do. You probably should stick to dry land, or charter with a licensed, safe captain.

My Garmin hand helds do not connect inside the house. My experience with either the Garmin handhelds or my HDS10 is excellent connectivity outside. When I first got my HDS10, I did not have the external GPS module connected. Under the hardtop, it took a few minutes to connect first time, but if power off during day and back on, it was within a minute.
When I connected the external module mounted on top of the hardop, it is near immediate connection to satellites. They claim it is a higher sensitivity receiver, so improves connectivity and tracking over the internal gps.
No issues with software. No issues with unit.
I saw the Garmin 5212 demo a couple weeks ago. While it was nice in how it will plot a course, just like my Garmin car GPS, it can not be safe in that is is plotting a course based upon the last map update, which does not always consider shifting sand bars, or changes by weather or tidal influence. I agree that is a very nice thing to have. That is where Garmin shines in my opinion is in map course. They do like the car GPS. However, I think the sonar and structurescan is top notch by Lowrance. Sidescan is very impressive! Detailed bait schools are incredible. Was able to find a school of cigar minnows a couple of weeks ago with structurescan. Dropped over sabiki into the school and bam! That is the first time I was able to actually get cigar minnows.
