Not Impressed

This product was defective and never worked properly. It wanted us to turn left when right was appropriate. The directions popped up and were easy to use so I think if the product was working properly, it would be a great buy. We sent ours back and chose another brand.
Great for the money!!

I bought this just before the holidays to see if I really needed a GPS for my travels, thinking that if I really needed a good GPS, I would spring for a more expensive model.
I found that there is really no need to update to a more expensive model! this is a great no-frills GPS. Sure, it doesn't have a hard drive or an .mp3 player, but it does everything a GPS should and pretty well at that. The unit is light and intuitive to use. It comes with a suction mount and lighter adaptor, along with an SD card loaded with maps. A nice touch is the built-in battery, which is nice for shorter trips, where you don't want a lighter cord cluttering your dash. the display, while not the latest or greatest, is crisp and legible in varying light conditions. The voice is easy to understand and is easy to pick-out in when I'm listening to moderate volumes on my stereo. Another review complained that the voice guidance does not tell you what street to turn onto, but I think that is a plus. Besides, the next turns are clearly displayed on the screen. There are several different map views as well, pretty much offering a street level display or a zoomed-out display, plus you can preview your route with a Mapquest-like turn-by-turn lists. Rerouting is also fairly robust, immediately re-calculating your route if you miss a turn. Sometimes, the unit does not provide the quickest route, but that is common with many GPS navigators.
My only complaint is that the SD card needs updating; I was driving on the West Coast of Michigan on a highway that was completed shortly after the maps were created and the GPS thought I was driving to corn fields (lol). Also, because of the card, POIs are a little off as well.
As for complaints about the GPS acquiring satelites, this is clearly explained in the manual:
How long does it take to establish a GPS fix?
The first time a GPS product is used (known as the first fix* or factory start), it can take up to 15 minutes to obtain a GPS fix. This is due, in part, to the following:
* The GPS product will spend time looking for the satellites it expects to be above its last known position, which may have been a factory in another part of the world. Only once it has realized it has been relocated, will it begin searching the entire sky for satellites.
* Depending on how long ago it was manufactured, the GPS product may need to download the `GPS almanac' (data that tells the receiver the approximate orbit paths of all 24 GPS satellites for the coming months), which may take up to 12 minutes.
The next time you use the GPS product, it should take less time to establish a GPS fix, as it knows the location of the GPS satellites.
*A first fix also occurs if the GPS product's internal battery has fully drained, or the GPS product has been transported a large distance since last being used.

I used the Navman 320 on a 900 mile trip. It worked perfectly. This is an amazing GPS unit for the price. Screen is clear and bright and it is very easy to program. It picked up the smallest details on turns and routes. I looked at the Tom-tom and Garman which were much more expensive. I'm sure they are good units also, but I can't see how they can provide a better GPS experience at 3x the price.
Good product for its price 2006-09-10
Got an ICN 320 just before the Labor Day weekend and got to use
it for our trip to Wisconsin. This was our first road trip
where I did not bring a map, I had to put our full trust on
this product during the entire trip.
Happy to say that it did not let us down. The missed-turn navigation is also useful since there were a couple of times
where I missed a turn (both intentional and unintentional). It
automatically redirects us to the new turns within a few
seconds.
Overall, there are still some features missing from this
product. But if you have a limited budget and all you need is
a basic GPS (plus some additional features) then this is
definitely a good buy.
Pros: Easy to use, quite accurate, missed-turn navigation
Cons: Turn-by-turn navigation does not include the street name (e.g. just says: turn left in 1 mile), limited POIs
Not good enough

I was really pleased to get the Navman iCN item, but getting it to work is a real problem. The first problem, if I set off for a new address I could drive to it, about 5 miles, without it establishing a GPS link. In other words no life except it saying "testing". The second problem, it seems to have a problem working out where it is, then when it does these appeares to the brain inside the box, an intersection, which gets no response at all. Still, it does make sense on longer journeys than short ones.
