I was using this unite in Abluquerque, NM 12-24-07. Several times it would tell me that it had lost all satellite reception. I had Wass enabled. I disable Wass and later it started working again. Is this an issue when you have Wass enabled or is this an often occuring problem with the 350 Garmin? What exactly is the benefit of Wass? When I turn the unit on it shows me that it is running America's lite base map 4.0. Software is 4.6
2008 maps. New unit. Is all this software current or does it need to be updated?

Sony Satellite Dish Antenna Operating Instructions
Operating a Sony satellite dish is a process that first requires correct dish placement to ensure strong signal reception. Additionally, the satellite receiver must be installed, and only then can you use it to put the dish in operating order via the use of its signal meter screen. Fortunately, you do not need to be a professional to complete these operations properly.
Initial Sony Satellite Mounting
Look around for a suitable mounting area for your satellite dish. This mounting area should be free of any debris and also allow for a flat mounting area. It's best to utilize a hand-held level to measure and make sure that your Sony satellite dish lies flush with the mounting surface beneath it. Also, look to the skies above before settling on a mounting area, as obstructions such as trees, power lines and tall buildings can block signal reception for your Sony satellite dish. Once a spot is chosen, go ahead and crudely aim your Sony satellite dish to the southern sector of the sky above. This will save you some time later when you return for further adjustments
If you shut the unit down - and remove it from the power cord in your car, this is expected.
When powered down, the unit is not capable of maintaining contact with the satellites in the sky. When you power it up, it needs to receive signals from 3 or more satellites get a "fix" or calculate your position in the world. The more signals received, the the more accurately displayed your position will be. The device must use the signal data, perform calculations and bring up a map of your area.
The "Lost Satellite Reception" message also occurs whenever the GPS does not have a clear view of the sky over the earth's equator. This can be from a garage roof to heavy foliage (tree cover) - and even when driving between tall buildings. Usually, it shouldn't take more than a minute or so (once the obstructions have been cleared) for the GPS to reacquire the signals, calculate and display your new position.
Press and hold the antenna signal strength icon on the display to bring up Satellite reception information. This will show you what, if any, satellites are being tracked. It will also tell you if you're in DEMO mode, in which case real satellite signals won't be used for the position.
Additionally, you can check the hardware by using the built-in hardware self-test features by pressing and holding the battery icon. Examine the information presented on multiple pages by pressing 'next'. Look for the hardware TEST button and press it. Wait several seconds for results.
These two steps should at least tell you where the problem is. If you ARE getting Satellite signals but they aren't being used by the hardware, you may need to reset your unit. Also check for firmware updates by using the Garmin Update utility available on their web site.
this could be that you are in a poor reception area, have you tried driving around to see if it picks up a signal elsewhere ?
The internal antanea may be faulty, does it have a socket to add an external ?
Has the unit got a reset switch ?
Make sure you are not moving and that you are on an open field with minimal aerial hindrances. It takes time for the GPS unit to acquire satellite signal and makes it difficult to acquire when you are moving so make sure you stop at an open are till it syncs with at least 3 satellites.
Signal Fade And Loss ~ Important, especially during winter!
Keep in mind that satellite broadcasts occur directly from fixed satellites in space to users. UPLINKS TO that satellite can happen from almost anywhere in the world! This includes broadcasts from remote studios, satellite vans and trucks.
Even signals from the main providing studios are susceptible to weather conditons even tho they have huge, high-gain transmitting dishes!
Weather is a major factor for both the uplinks and downlinks! Storm clouds can block the signals anywhere in the signal path(s). Rain clouds do too ~ even if it's not raining yet. Water-laden clouds make some of the BEST signal attenuators.
So one may have a gorgeous day in San Diego (let's say), but storms back east could trash satellite reception at his location and potentially everywhere else!
As you know, weather conditions all over the US are changing constantly with many severe storms occurring this past week and during any winter. In fact this week there was total signal loss on several satellites and I suspect storms back east were a big factor.
So it could have just been issues of timing for you. The UPLINK had intermittent problems with signal paths semi-crippled by weather... YOUR weather was CLEAR, but your reception was far from problem free ~ only because of weather problems elsewhere.
If you see intermittent satellite reception do check out the weather... especially back east.
Hello sothypaw, In order to receive satellite signals your GPS receiver must have a clear view of the sky. If you are using the GPS inside of a vehicle the body of the vehicle may shield the unit from receiving these signals. To minimize this the GPS should be mounted at the lowest place within the automobile that has a clear view of the windshield and side windows. If you continue to have problems then you might consider purchasing an external antenna for use with the GPS. Even with a properly mounted GPS you may occasionally lose satellite reception due to local terrain (hills, mountains, dense forest etc.) or other obstructions (parking garages, tunnels, etc.) which can block reception.
