Thread: Igo Primo GPS Lag, GPS Delay, GPS Offset, Position Error

Hello,

First of all sorry for the very long and repetitive thread title. While using Igo Primo 9.6.13.405512 in my double din car unit (256MB RAM and 800 MHz CPU) without any extras (dem, tts, ux, skin) I noticed a delay in voice guidance.

When I approach a junction Primo says "After 50m, turn right", but actually there is 20m distance between me and the junction. My position on the map is also a bit back of my actual position. Roughly there is an offset of 25m. When I reach the juction and stop, the position info on the map is totally correct. My speed is aroun 50 km/h by the way. The problem is apparent in city driving but do not bother in highway while I'm over 100 km/h.

In some forums I saw a paramater under [gps] section, "delay". Typical values are 100, 250, 500 ms I think. Has anybody had a chance of practical test of this parameter? Or have any ideas about this GPS lag?

Thanks in advance.

As an extra info, I also tested Mireo Don't Panic on the same hardware but the lag is obviously less than Igo Primo.
