Hi Marvin,
First a detail. It's not a problem in the nav software, as far as I know. That's an important distinction. Perhaps because Garmin sells map products seperately from their nav hardware and software it is easier for me to make the distinction between maps as a seperate product from the nav software. Eg. I can buy an upgrade to a completely new set of map data for my Garmin iQue 3600 without buying a new iQue 3600 or an update to its nav software. Conversely, I can get an update to the nav software without buying new maps.
To answer the question I think you wanted to ask, Yes, the Garmin map products that are based on Navteq data have had similar types of problems for as long as I've had my Garmin GPS (4 1/2 years).
I did a further check and I have determined that the specific "ernest ave" problem also exists in Garmin's Metroguide Canada map product, which is built on data provided by DMTI, not Navteq.
I also did the "regent ave" test from George's original post and was able to duplicate George's results with S&T 2008 (Navteq), Garmin Mapsource searching City Navigator North America v8 (Navteq) and Metroguide Canada v4 (DMTI).
I checked both addresses in an older Garmin/Navteq product, City Select North America v5, which is a precursor to the City Navigator product. This product is five years old so that makes the data closer to seven years old. I get the same results for both addresses, with one small exception. When I type in the full "regent ave" search I don't get "regent ave" but I do get a "regents ave".
Finally, I did both the "ernest ave" and "regent ave" tests with both Garmin map products (CNNA v8 and MG Canada v4) on my iQue 3600 and duplicated the results there as well. (This matters because the search software is different again from S&T or Mapsource but the underlying map data would appear to be from the same ultimate source).
So it appears that the root problem may be in the data created by some urban authorities, in this case the cities of Winnipeg and Toronto, when they enter their civic address information. This is the data that would be acquired from cities and towns by any map-making company like Navteq, TeleAtlas, DMTI, etc.
Again, it doesn't solve the problem but I hope it at least contributes to a better understanding of the possible root of the problem and why it is so difficult for the nav vendors (MS, Garmin, etc.) to have fixed. It's not a problem of their making so they can't fix it themselves.
In this particular case it's quite likely the problem is not even a problem of the map data providers (Navteq, et al). It looks like it is a problem created by the people who originally input the data (whoever does the geomatics work for, in this case, the cities of Winnipeg and Toronto.). And it might only be repairable at that level.
At the end of the day, your solution is the easiest. Just get into the habit of never putting in "ave", "st", "road", whatever. That's what we Garmin users have been doing for years.
