Anyone using iGO 8

For me, I have faster locks, see more sats and more locks with data on than when it is off. Whether that's due to AGPS or not, I know there's a difference. I'm in Vancouver, Canada if that makes any difference, on Bell as well using 20273 rom made from the kitchen. I tested pretty much with iGO8/OCN8 only and look at the sat viewer. With data on, I'd be getting 6-9 sats locked and they were of strong strength but with data off (blocked by no data) the most I would get after a cold start is only 4-5 locks, avg is closer to 2-3 locks only. It would also take forever to get a lock but it does lock. That's why I think data is needed for better GPS signal. Whether that's AGPS or not I'm not sure, if it is, then I guess AGPS needs data, if not then like I said in other posts, there's something else that affects the signal we get.

Here's a good tutorial on GPS vs aGPS - I didn't know much about it before I read it. Whether this would incur a data charge when I'm roaming in Canada depends on a) what aGPS configuration the vogue works on, and b) whether the cell tower - phone communication occurs over the data line or not. Your testing would suggest that the cell tower "assistance" is using a data route.

I turned off aGPS by using a program called Advanced Config. It is included in many custom roms, can be dl'd too. I also turn off my data when I go to canada by preventing data while roaming - for reasons other than just the aGPS. The only thing I've found with iGo8 is that with aGPS and data off, I typically need to soft reset before using it or it won't get a lock, don't know if this is because it is trying to use old sat info, or because I just got impatient the first couple of times and then began soft resetting after that. But yeah, I would get a lock in about 2-4 minutes with that config, and dropped sats about every 10 mins for 20 seconds or so.

But your testing might also indicate that I don't kneed to turn off aGPS, I can probably just block my data connection and have the same results. I thought that maybe the phone would be "searching" for that assisted information and then maybe not function at all; apparently that's not the case.

Definitely while I'm home in the US I keep aGPS on, and have seconds to a sat lock and almost never drop a signal. I only disabled it cause I was going to Canada.

I did not try simply disabling data but leaving aGPS on, as I assumed it wouldn't work anyways. The next time I go to Canada, I will give this a try, and see if I lose satellites all the time and/or if my TTFF dramatically improves; from what you say, though, it's probably the equivalent of turing aGPS off.

thanks for the article, it's very informative. It didn't say much about whether the assistance is done via data or not but seeing as we have the gpsone chip and there's the pde ip address found under the gpsone settings, leads me to believe that we need data for aGPS. I didn't build advance config into my rom so I guess I can't change it. Do you happen to know if the advance config is the advance config(Schaps config) found in the kitchen? Do you know what it does, like does using it change the registry settings? maybe it disables assisted gps that way. I just don't want to rebuild/reflash another rom if I can just do the same thing by changing the registry as with advance config.

Yeah, I'm using Schaps 2.02.1. I think it is just a nice UI to change registry settings, as I have changed reg settings using dotFred reg edit and then noted the corresponding change in Schaps; it may also be able to add registry settings for certain options, I don't know. You can find it as a cab, if you really want it. Take a stroll through the registry, see what you find.

(very fancy Advanced Config found here, not the one I'm using)

I would also like to know how to import contacts. I did not have maps when IGo was installed, so did not find contacts. Tried reinstalling, soft reset, etc. I also use TomTom 7, which is easier to add contacts.

Igo automatically imports my contacts as I add addresses to them

So, even if you add a contact after program is installed it shows up? I'll try that and get back.

that may be true. it prob can only operate in one mode at one time so it may take time to switch modes or it might take a reset to do so. prob not a huge deal as long as it worked in the end.

Yes. Each time I add a contact it will add it. Sometimes it does not do right away, don't know if this requires a soft reset, but if I recall correctly from the last time I added a contact address, it does not.

[jmckeejr]

I got it to see the contacts by changing the addresses. Still has geotracking error on some. This is strange because when I searched for the address in find, it found it on the map. Checked spelling and appreviations, but everything looks in order.

[tatnai]

This happens to me as well, something in the importing of the address things sometimes get messed up. Don't know why. Anyone?
