I've only had my unit for a week+, but in that time it could not find a satellite about 80% of the time. Is this a poor antenna issue or is this just a bad unit? There is no antenna that I can see on the unit, so I assume its internal.

If after reading the above article your unit is still having problems, please ensure that your unit's software is up to date. You can do this by using our WebUpdater® program.
If you have tried all of the above suggestions and your unit is still not acquiring satellites, you can perform a master reset by doing the following: Note: A master reset will erase all waypoints or favorites and will restore your unit to the default factory settings.
Start with the unit powered OFF and unplugged from power.
Touch and hold the bottom right corner of the touchscreen.
Power the unit ON and continue pressing the screen until a new message displays, "Do You Really Want To Erase All User Data?".
Touch Yes and go through the set up again.
Take the unit outside and let it set with a clear view of the sky for 3-5 minutes to acquire satellites. If the unit still does not acquire satellites after this, please contact Garmin Product Support.
Have you tried a complete reset? If not this is what you do. Turn on the Garmin at the same time press the bottom right hand corner of the screen. this will return it to factory standard, but it will wipe out any information you may have stored on it.
You need to do a complete reset by turning it on and at the same time press the bottom right hand corner of the screen this will reset it to factory condition. having done that when you switch it on again leave some where where it has a clear view of the sky and leave it for about 1/2 an hour. This should sort it out for you. Best of luck.

As GPS units are used, data is gathered which
helps them acquire satellites quickly at the start of each use. If a device is
used daily it should be able to acquire satellites in a minute or less. Using a
GPS device while it is outdoors with a clear view of the entire sky is the
ideal condition for acquiring satellites. Please know that there can be several
different factors that may cause a GPS unit to not acquire satellites:
If your unit is trying
to acquire satellites for the first time, it may take longer than normal
to establish an initial position. If the unit is powered on and outdoors
with a clear view of the sky this should not take more than 3-5 minutes.
If your unit has not
been used for an extended period of time (more then a month), it may take
3-5 minutes to acquire satellites.
If your unit is indoors,
it may not acquire satellites. Even standing next to a window indoors will
block a majority of the sky which is needed for a device to locate and
lock onto a satellite signal.
If you have just
finished updating the software in your unit or you have performed a master
reset, your unit may take 3-5 minutes to acquire while outdoors as the
data that is used to locate satellites may have been erased.
If your unit has
traveled over 500 miles while turned off or not tracking your travel, it
may take 3-5 minutes to acquire even in ideal conditions.
If your vehicle has a
protective coating on its windshield or electronic devices which interfere
with the unit receiving signal, your unit may need an external antenna* in
order to acquire satellites.
If you suspect this to
be an issue, try taking the unit outside of the vehicle with a clear view
of the sky for 3-5 minutes so that the unit can acquire satellites. If
your unit loses satellites once moved back into your vehicle you will
most likely need an external antenna*.
If your unit is still having trouble acquiring
satellites, please ensure that it has the latest version of operating software
by using our WebUpdater program. Once
your unit is updated please allow the unit to acquire satellites outdoors in a
stationary position with a clear view of the sky.
Question: Why won't my unit acquire satellites?
There are a several different factors that can cause a GPS unit to not acquire satellites:
If your unit is indoors, it may not acquire satellites.
If your unit is trying to acquire satellites for the first time, it is normal for it to take a while to establish its initial position.
If you have just finished updating the software in your unit or you have performed a master reset, your unit may take longer than normal to acquire.
If your unit has traveled a long distance while turned off or not tracking your travel, it may take a longer period of time to acquire.
If your unit has not been used for an extended period of time, it may take a longer period of time to acquire.
If your vehicle has a protective coating on its windshield or electronic devices which interfere with the unit receiving signal, you may need an external antenna.
If your unit is not acquiring satellites, it is recommended that you place the unit in a stationary position where it has a clear view of the sky. In some cases it may be necessary to take the unit outside of your vehicle as certain vehicles inhibit the unit from acquiring satellites. As the unit receives signal from the satellites, it will begin to lock on to them individually until it has acquired enough information to establish your position.
If your unit is still having trouble acquiring satellites, please ensure that it has the latest version of operating software. You can do this using our WebUpdater program which can be found at the following link:
Take the unit outside and turn it on. Then select View Maps, at the top of the screen it will say either "Locating satellites" or "Acquiring Satellites". Once the garmin has locked onto the overhead satellites, then it will say "Ready to Navigate".
Locating Satellites take longer than Acquiring Satellites.
