Well, still nobody talking. I guess I'll get on out with it. In an unplanned purchase, I went ahead and bought the Rikaline GPS-6031-X7. I looked at both and they seemed to have similar enough features that I just ended up getting the cheaper one, by about 10 bucks. But I managed to break off one of the metal battery connectors and was unsuccessful in soldering it back on (I hate that stuff) so instead of messing around with it, I decided to grab the HOLUX GR-231 since I was in a hurry to get my GPS up and running again before the weekend. It also allowed me to do a mini-review and comparison of the two. (I'm probably gonna throw the rikaline on ebay for a few bucks for anybody who wishes to fix it themselves and get it working or see if they can get a warranty repair on it, yea I'm impatient)
Notes: Real driving testing involved was used pairing the devices with my Dell Axim X30h, but I also managed to get both working with my future carputer:
Longer battery life
Multiple devices can connect to it (pda & carputer simultaneously)
Automatic detection of BT to connect & turn on (works great on carputer!)
Automatic turn off when BT drops (when I exit Iguidance 2.0 on the carputer, the GPS automatically turns off, when I run Iguidance, even embedded, it automatically turns the BT device on)
cool colorful changable wings! lol
Well, I did break the battery terminal.
NO on/off switch which proved to be a slight problem because -
I had connection issues with Dell Axim PPC...worked great when it did, but I was losing BT connection and it wouldn't reconnect unless I reset both devices. No off switch on the GPS required me to keep sliding open the battery cover and removing the battery and reinserting it, which lead to broken metal clip.
Indicator lights not as informative as the Holux.
No external antenna plug.
Can ONLY be connected via BT.
Seems to have a faster fix then the Rikaline.
Definitely picks up a signal better (even getting in indoors) and had no problem driving around with the GPS in my pocket, I didn't even have to put it on the dash.
Can be used with BT or usb cable (purchased seperately).
It can be charged via the AC travel charger, the car cig lighter socket, or any USB port - the cable seems to be a standard usb cable that plugs into each of these devices.
Has an external antenna port.
Indicator lights will tell me if it has a satellite lock, and I can tell if it has a BT connection or if it's waiting for a BT connection.
Power switch proves helpful.
Supposedly has power save mode to turn off GPS after 10 min if no BT connection is detected.
Uses the same type battery of Nokia cell phones (although they claim their battery is more heat resistant).
Has a heat protection circuit to stop charging battery after it reaches a certain temp.
Can't be connected to both PPC and carputer simultaneously and still testing on how fast/feasible it is to switch between the two. (I plan to use it mostly in my car paired with carputer, but I want to be able to disconnect the unit to bring into my girl's car and pair it with my Dell Axim).
Power save mode doesn't appear to be working properly, and it hasn't turn off for an hour as of now hehe - but at least it has a damn switch to turn it off!
Switch is software based, not hardware (have to hold it in for 1 sec to turn on, 2 sec to turn off).
Battery life isn't as long as the Rikaline's. (not that it matters much to me, 9 hours is good enough).
Since it's a single usb cable that plugs into the head of either the ac travel charger or car cig light outlet, I can't keep two seperate cables in both areas, but if it's a regular usb cable I will just pick one of those up.
I still have a lot more testing to do, but as of now, I can only test the Holux, so expect to see any further rants on this item on this thread, but as of now I prefer and like this item better then the Rikaline unit.
