Just had a look on ebay and.... Garmin Etrex's (The yellow one like mine) are going for ~ £50 or Garmin Geko 201 (New version, smaller - 101 is not usable!!!) ~£45An alternative to these are the Bluetooth GPS units which seem to be going for ~£50 on Ebay, Try to get one that takes AA or AAA batteries and buy yourself a good NIMH charger and batteries from 7dayshop (See memory card links below) Or you might want one with a car power adaptor. obviously no stand alone unit, but you can shove the gps unit in the hilift box and have a "Clear" view of the sky, and the Ipaq would still work around the car (~10M max)I had a look for CF and SD GPS cards but they seem really expensive for a half reasonable one. be careful Ipaq 2210 ~£170 1gb SD £49 - http://www.7dayshop.com/catalog/normal_ ... rds=1gb+sd, might be cheaper on ebay1gb CF £52 - http://www.7dayshop.com/catalog/normal_ ... rds=1gb+cfyou could probably get away with a 512mb of either type. Link cable for either GPS is available here http://gpsbitz.co.uk/gpsbitz_store/view ... oduct=I38E for £30 + Postage I guess.If you are a dab hand with a soldering iron, then http://www.nomad.ee/micros/etrex.shtml and http://pfranc.com/cgi-bin/pub/c_uk/Garm ... ?pid=ePlug are useful links (first on is wiring Diags, second is where to get a decent GPS Connector for) This is where I got my cable from http://www.psionleads.freeserve.co.uk/prices.htm £50....! These are probably useful if you want to connect to your GPSIII (or was it a 5) on the dash too.
Thats where Im coming from Well, you see it's like this.....Some of the PDAs are only 32Mb and some even smaller than that.... this means that you can't run as much at the same time as you run out of RAM. same with the processor speed, the Ipaq 1710 only has a 203Mhz processor... so half as fast... especially when you have just taken a wrong turn and want it to calculate a new route for you....It's all down to 1s and 0s....4 nibbles in a bit8 Bits in a Byte1024 bytes in a Kilobyte1024 Kb in a MegaByte1024Mb in a GigaByteBesides, the paper map won't shout Turn left at the next roundabout.Tomtom got me all the way down past Grenoble last year (10 hours) without a wrong turn. and all the way back too. Past Paris as well. And I didn't have to get the girly to read the map once.... (Let alone try and turn it round so that it faced the way we were heading)
