Hello Pete, No. Since I didn't quite know what I was doing, I may have made changes that shouldn't have been made and it was the easiest to just restore all default settings to clear up things rather than figure out what particular setting was incorrect. It sure seems to be a very good unit. I have no grounds to compare it though because this is my first ever GPS. But I am extremely happy with it. As to the price, it is significantly less expensive than a similar Garmin unit, so it's not bad at all and it comes with very many accessories. The only one thing I needed to pay extra for was the serial cable. It comes with the North American Jeppesen information, but you can purchase world wide coverage for extra. It uses an MMC (or SD) card to store information not in memory. The card works like a floppy disk. It comes with an MMC card reader which works like a floppy disk drive and it's not only a reader really, that's just its name. It's a plug and play device (using Windows 2k or XP) and you can copy files to and from it or erase those files just as if it were a floppy disk. Very handy and makes it very easy to back up staff.

Hello Pete, I contacted Lowarnce and they said all I needed to do was to reset the GPS. It worked, so everything is is fine now. They also said that the answer to your question (What makes the GPS use the NMEA data received via the RS-232 cable rather than the satellite data?) is simply that the NMEA data has higher precedence. Thank you very much for trying to solve problem that (as it turns out) wasn't even a problem on your side. I learnt a lot from it! Regards, Gabor

Pete, I think you are right. I will try to fgure that out and I'll get back to you. Thanks for your help so far!!! Gabor

Hello Pete, Thanks again for your quick response!!! You are right, unfortunately the documentation of the AirMap1000 is inferior to the product itself. Based on the photo I just took (http://johanne.is.dreaming.org), the unit understands the following sentences: GLL, GGA, APB, RMC and RMB, GSA and GSV. I am not familiar with these, just starting to do my research on the internet. But the fact that RMC and RMB are listed as one option suggests that RMC in itself (which is supported by GPSout based on its INI file comments) would not work. Similar should be the case with GSA. Since your documentation says that listing more than the necessary sentences "[is] not very efficient, but useful to determine whether the target program supports any of these", I set senteces to GLL,GGA,APB. Unfortunately this does not seem to help. Once again, thank you very much for your help! Regards, Gabor

Pete, First of all, please accept my apologies for calling you Peter (as you were listed on some web site where I found you) instead of Pete. Secondly, thanks very much for the quick response!!! Thirdly, you are absolutely right, I mistyped the "Sentences" entries. My GPS does recognize NMEA input. (Just in case you are interested in the unit, you can find it along with a full downloadable user manual in PDF format that proves this at http://www.lowrance.com/Aviation/Products/AM1000.asp) The last entry (VTGGGA) is clearly missing a comma, but the incorrectness of the first two entries is a bit confusing. 1. The gpsout.ini file I downloaded with GPSout contains the line Sentences=RMC,GPRMZ eventhough GPRMZ is not listed in the comments as a valid entry. I assumed that it was valid. Should it be removed? 2. PGRMS is listed as a valid option in the comments of the gpsout.ini file. Is it not? What do you suggest that I do to make this work? Once again, thank you very much for your help and quick response. Regards, Gabor

This message is primarily for Peter Dowson, but any help would be highly appreciated. Peter, I was trying to use my Lowarnce AirMap1000 GPS with Microsoft Flight Simulator 2004 yesterday. The GPS unit cannot aquire the position. Speed is set to 9600 on the GPS. My gpsout.ini file contents (without the comments): [GPSout] Sentences=RMC,GPRMZ,AV400,RMA,PGRMZ,GLL,VTGGGA,GSA Interval=1000 Port=COM1 Speed=9600 I rebooted the machine and the GPS but that did not help. Questions: 1. I have two serial ports. How do I know which COM port to set in the gpsout.ini file to point to the one I plugged the cable in? 2. If the gpsout.ini file changes, what (if anything) do I need to restart for the changes to take effect? (fs9.exe? GPS? windows?) 3. Does it matter what the order of start up is (for example fs9.exe first and GPS after or reverse)? 4. How can I confirm that data is being sent to the GPS (therefore the problem is on the GPS side) or not (therefore the problem is on the GPSout side)? Thanks for your (or anybody's help)! Gabor
