This unit (I have one) worked fine when only 6 characters were used in the GC codes. When they were running out of possible combinations and went to 7 characters, this is what happened. Before I got a more up to date unit, I wold edit the codes to remove the first G and then the rest of the code would fit. You can either live with this condition--if you're only doing a few caches occasionally-or upgrade to a more modern unit. Edit: typo Is there easy way to do the edit?

[quote If those caches are present in the unit, you need to alter the (name) field to reflect the proper cache. I cant get the three in, they overwrite the previous one so only one there no matter how many times you try to load all three

Kind of noob, done a few caches,, got a clone data cable now working ok. Some issues with chrome on plug in , ok on old internet explorer. When I transfer a few cach locations to device I see them appear on the waypoint list and get Transfer Complete on unit display no drama. So daughter and I thought we will load 3 caches, all done by same guy and they have ID nos that only differ by last digit of ID. All along a short walk, probably created at same time. First one goes in and I see it. Second one goes in and I don't see it. (just looks like the first only ) Third one in and no change to display ( still one entry, looks like first one still ) Open the only one there and its the last uploaded one ( the third one ) As the Display ony supports 6 leters/Nos the last digit must not be checked during upload and the SW overwrites a file that has the first 6 letters ( of 7 ) the same. The locations were.. GC5JVAH GC5JVAE GC5JVAB Display only says GC5JVA After upload of all three!!!!!! Any way round this code design oversight....

WAAS was for north American aviation, although it is mainly, currently used in shipping and farming. neo 7 SBAS + PPP (GPS): < 1 m CEP as is neo 6 also. You do need to stand still and allow the carrier phase averaging to converge. You would benefit from a reasonable phase centre antenna like some of the old Sarantel designs. http://www.u-blox.com/en/gps-modules/neo-6p-/neo-7p.html Steve

ublox neo 7 modules will do sub 1m - provided you use gps, egnos (sbas) and their ppp carrier phase averaging - you need full clear sky view and a few minutes of being stationary, In the uk with an old etrex yellow with the WAAS on you get about 6ft radius error - you need to hold the unit level and still. The original use for WAAS was for north American shipping. The data format is the same in the Egnos Europe sats - So put WAAS on and you decode Egnos and go from 20ft radius error to 6ft radius error. sat 33 is an Egnos., in the low south geostationary. Helps if you aim your screen towards the satellite to get a faster initial decode Steve
