hlthtcher Posted January 9, 2004 Share Posted January 9, 2004 I have a Sportrak Map that I got a few days ago. I updated to ver. 4.06 from the Magellan web site. I've noticed a few things that I would like to know if it's normal. 1) I've set the unit to verify shut down when the power key is pressed. When the text comes on to verify shutdown (by pressing the enter key) some of the text is unreadable (doesn't fit on screen). Anyone else have this? 2) When I go to the sat. screen on the bottom where the numbers for the 12 sat. are I don't have all 12 listed... sometimes there are 8, 9, 10. Are all supposed to be there even if not getting rec. from them? 3) On some nav screens when in the sun some of the darker areas seem to flicker or look wavy. I don't notice it really while inside or in the shade. Is this normal also? Thanks for your replies....yes I know I am OCD!!! Quote Link to comment
otr Posted January 10, 2004 Share Posted January 10, 2004 Well, #1. Im running 4.02. Mine does the same when verify is on. #2. Mine lists all that should be available. Im looking now and it lists 12, with 2 available in the house, but Im prety sure that at times Ive seen less. #3. Try adjusting your contrast. If I am understanding you correctly, it just sounds like the refresh rate of the display. It will be more noticable in bright light. kris. Quote Link to comment
hlthtcher Posted January 10, 2004 Author Share Posted January 10, 2004 Thanks Kris for your reply. Anyone else experiencing the same things with their GPS? I just want to make sure I don't have any problems. Quote Link to comment
EagleI Posted January 10, 2004 Share Posted January 10, 2004 There are actually 24 (27 counting backups) GPS satellites out there. They are in earth orbit, not stationary, so how many and which satellites you will pick up from your location is not a constant. Your GPSr can track a maximum of 12. See How Stuff Works for more information. Quote Link to comment
hlthtcher Posted January 10, 2004 Author Share Posted January 10, 2004 So, let me get this straight. There will be times that I will have 12 satellites listed on the bottom of the sat. nav screen, that's because my GPS "sees" them. I may only get reception from lets say 5-6 which is good. Now there will be other times that I will only see 8 satellites listed on the bottom of the sat. nav screen this is because my GPS only "sees" 8. I may get reception from 4 of them. Your saying this is normal and nothing to worry about? So If I see the sat. number dissapear from the bottom that is o.k.? Quote Link to comment
peter Posted January 10, 2004 Share Posted January 10, 2004 Almost. Your receiver gets almanac data that allows it to predict where all the satellites in the GPS constellation are located. It will only attempt to receive signals from those that are sufficiently above the horizon from its last known location. Those are the satellite numbers shown on your screen. Sometimes there will be 12 or more satellites visible from your location and the receiver will try to get signals from the best 12, but other times you'll have fewer satellites above the horizon and you won't see a full 12 satellite numbers shown on the screen. What the receiver doesn't know is which satellites may be obscured by buildings, hills, your body, etc. so it tries to receive signals from the satellites it expects to have over the horizon but usually won't actually get a signal from all of those. That's why only some of the listed satellites show a bar indicating the signal strength (or more precisely, the signal-to-noise ratio). Quote Link to comment
+SBPhishy Posted January 11, 2004 Share Posted January 11, 2004 This is very strange because as far as I know, there is no 4.06 upgrade from the Magellan website for the sportrak map. The current firmware upgrade that they are offering is 5.0. Maybe you are using the sportrak pro firmware? That could be the problem. Quote Link to comment
hlthtcher Posted January 11, 2004 Author Share Posted January 11, 2004 SBphishy check this link out. This is what I used and my GPS says 4.06. My Webpage Quote Link to comment
+OurWoods Posted January 11, 2004 Share Posted January 11, 2004 5.0 Update for the ST Map Quote Link to comment
+SBPhishy Posted January 11, 2004 Share Posted January 11, 2004 Well shut my mouth... version 4.06. How did you ever find that? Check out OurWoods link. Thats what I use. Quote Link to comment
+SBPhishy Posted January 11, 2004 Share Posted January 11, 2004 Hey OurWoods, do you use 5.0? Do you have any problems with it? Quote Link to comment
+Rosco Bookbinder Posted January 11, 2004 Share Posted January 11, 2004 Hey OurWoods, do you use 5.0? Do you have any problems with it? I updated my Magellan SportTrak Map to 5.0 just after I got it a couple months ago. NO PROBLEMS Nothing has happend that tells me it's a buggy version. I did notice the menu changes and not sure they were better but I've gotten used to them.. Quote Link to comment
hlthtcher Posted January 11, 2004 Author Share Posted January 11, 2004 Hey, Rosco, SBPhishy, and OurWoods: Do you guys ever experience what I wrote to begin this thread about the text on the shut down screen and only having 8-10 satellite numbers listed at the bottom of the sat screen? Oh, by the way I did a google search to find 4.06 . Quote Link to comment

I guess I don't have my receiver set for the verify you are talking about so I don't know about that problem but I believe the most sats I've ever had show is 7 or 8 which is 4 or 5 more than you would need anyway.

omegaalphaone Posted January 12, 2004 Share Posted January 12, 2004 Do the firmware updates work for the UK version or is it just a US thing? Quote Link to comment
