    Does this exist? I would like to buy one. But, when I see prices from $79-299 It is a little confusing.

    Mainly, I would like a reciver that can be charged and used without having a perminet connection to a charger.
    thanks for the help

    I use and highly recommend a bluetooth GlobalSat BT-338.

    I got from Semsons for $179. Works great outdoors. Works pretty well in cities as long as you have a clear view of the sky. If you are walking on a city sidewalk with a sky scraper right next to you, it wont lock well. If you are on the edge of the sidewalk closer to the road than the building, it'll lock fine. (This is normal with all GPS in the city)


    I use it for GeoCaching and getting unlost when im traveling. I use CetusGPS and CotoGPS with it. I will buy TomTom 5 when it is available.

    Globalsat bt-338 - bought from Semsons

    Came with a nice leather belt pouch, and a free pda car holder too. The pda & holder are too heavy for my cheap car vents.

    Also a dc car AND ac wall charger. I wasnt expecting both. GlobalSat does a quality job. To charge, just plug the cord to the wall, and the other end into the GPS on the side. More than 15 Hour battery life!!

    I also use the GlobalSat BT-338. Although I have not yet used it for GeoChaching, I do use it heavily with TomTom Navigator 2004 in my vehicle. I must say that I am very impressed with it's performance. I also purchased my GlobalSat BT-338 from Semsons and would recommend them to anyone whishing to purchase a Bluetooth GPS and/or navigation software.

    You get what you pay for with many bluetooth GPS receivers. Personally, I have the GlobalSat BT 338 and what makes it great is the long battery life, small form factor, superior sensitivity (SirfStar II), reliability, etc...

    Has anyone else noticed that the Treo 650 will drop the bluetooth connection with the GPS unit ( Globalstat BT-338) if you wear them on your belt on opposite sides.i.e 180 degrees apart? I had this happen while using Intelligolf to survey a golf course. I lost the bluetooth connection between the GPS and the Treo 650 a number of times. If the two devices are next to each other, bluetooth connection is continuous. Is the 10 meter range of the bluetooth GPS line of sight?

    I don't mean to thread jack, but I don't think that the bluetooth radio in the Treo is that powerful. I have problems going more than a couple of feet when I'm using my BT speakerphone.

    Thanks for the reviews on the BT GPS receivers. I've been looking for one myself. Has anyone used the Altina GPS unit? I saw one on ebay here:

    I also own the GlobalSat BT-338, bought from Semsons with TomTom...excellent combo!

    I cancelled an order for TomTom BT and have ordered the BT-338 instead - will receive it tomorrow. I appears to be the only BT GPS device on the market with the Sirf III chipset, which means 20 channels instead of 12, longer battery life and more sensitivity than most other devices. It apparently can work indoors in some situations.

    I have had this happen a few times. I can be in a different room than the bt-338 or around the corner and itll work. Have my phone in front, and the bt338 on the back side of my belt, and i get no gps.

    I thought fat passed radio waves better :P

    Do we need to lose weight?
    I tried several tests both indoors and out. Indoors, I can turn my back on the BT-338 GPS and get a signal on my Treo 650. I suspect the radio waves are bouncing off the walls of the room. In the same test outdoors, I drop the bluetooth signal as I turn around. So the bluetooth radio waves must be blocked by human bodies. I understand that the BT radio waves will not pass through metal, yet I have seen in this forum, people claiming that they can put their BT GPS in their car's glove compartment and have it still work.

    Anyone care to chime in?

    I have downloaded Cetus GPS and it is a good program! I have one problem. I downloaded and tried both version 1.1 and version 1.26b7. Neither version shows the arrow in the circle. The circle is there showing N,S,E and W and it does rotate as I go in different directions but there is no arrow pointing to the direction I'm going in. I have a Treo 650. Does anyone else have this problem?

    The circle shows where you are going. The arrow shows the destination in reference to where you are going. You need to goto "Position" make a new position, and then press GOTO.
    Once you start traveling in a specific direction (say south) the S in the circle will rotate to the top of the screen. That pretty much messed me up for a bit until I realized how it handled itself. (Much different than CotoGPS).
    I use Cetus since I can convert and download GPX and loc files to CetusGPS PDB databases with gpsbabel. I wish it handled copying and pasting coordinates better but you cannot have everything.
    (I made a little cgi-bin web interface between my Geocaching.com pocketqueries and gpsbabel so I can download new gps file waypoints from the site, and then upload and convert my gpx files to pdb anywhere i need. )


    -- On the glove compartment topic... mine does work from my glove compartment, since it is mostly plastic. The reason I do not use it in there all the time is the sleep mode. If my Treo is off or out of GPS mode for a long period of time (like if im on a call) the bt338 will goto sleep/power off. I have to turn it back on again. As long as it is getting bluetooth communicaiton itll stay on though.

    Sort of OT but can someone tell how much memory does TomTom's maps take on the SD. Need to decide which SD should I go with - 512 or 1gb. 512 is of course a much better deal. I don't need the whole US on SD but a few states that I may travel - CA, and NV.

    need to get an idea how much of other data I can fit into the SD along with the maps.

    How about receivers by Holux, anyone use them on the Treo 650 and how well did they work? PS, Sklim, if you can afford a gig, go for it....

    just received my GLobalSat 338 and can't get my Treo to see it. Is there a trick? I've tried several different configurations with no luck. Seems like it would be straightforward.
    hmmmmmmm, any ideas?

    Just want to check-- does the GlobalSat 338 work well with Mapopolis (on a treo 650)? Thanks.
  17. #17  
    Yes,
    I have been using the Globalstat BT-338 with Mapopolois on my Treo 650 since April. It works great- no issues

    Err....I believe this should say SirfStar III.
