I've tried a few of the laptop GPS programs with my hacked Netpliance I-opener and with a Pentium 166 laptop.
1) DeLorme Street Atlas 6.0 w/ Earthmate GPS
2) Sony SkyMap 2000 w/GPS (serial version, NOT PCMCIA)
3) Rand McNally Streetfinder 2000 w/GPS
DeLorme Street Atlas GPS AND I-OPENER
GOOD
- For those of you considering getting a GPS for the I-Opener, the GPS with the DeLorme Street Atlas can run off of 4 AA batteries. The other 2 GPS units take their power from the laptop's PS/2 port.
- You will need to convert the serial connection to USB to work with the Iopener.
- The I-OPENER only cost $100, plus an extra laptop hard drive
BAD
- While the I-Opener is a self contained computer, the screen is passive matrix and hard to read in direct light.
- However, having had my I-Opener in the car for a few months, I finally took it out. Having a color monitor with a full computer in the car is a cool tech toy, but it's difficult to mount, to supply power to, and is not the kind of thing you want to leave while parked in New York or at the mall parking lot.
GPS and PENTIUM 166 LAPTOP
DELORME STREET ATLAS W/EARTHMATE GPS
GOOD:
- Good, accurate map
- does not use alot of CPU horsepower
- can be powered by AA batteries or laptop port
- GPS program works with other GPS units
BAD
- The GPS unit broke after 4 weeks
- GPS unit does not output standard NMEA sentences.
SONY SKYMAP 2000 W/GPS
GOOD
- Accurate map
- smallest unit (size of a pager)
- although I had the serial unit, I would think that the PCMCIA port is good because you don't lose the use of the serial port or the PS/2 keyboard port.
- The speech feature was ok, but got old quickly
BAD
- The coverage of the ETAK service is limited to major cities. (In the New York area, I got alot of traffic advisories and alot of them were on routes that I were out of my region of interest and I didn't find it too useful.)
- Included GPS does not work with other programs.
- Program requires took alot of horsepower, as compared to the other programs, the screen redraws were slow.
RAND MCNALLY STREETFINDER FOR LAPTOPS
GOOD:
- Maps are easy-to read
- GPS unit outputs standard NMEA
- primarily good for moving map or for kids
- cheap at less than $100
BAD:
- Map was accurate in New York but very inaccurate and unusable on a recent trip to Hawaii
- Hard to use for door-to-door directions (not for navigation)
- Minimalist. Not as full featured as DeLorme or Sony products.
FUTURE PLANS
RAND MCNALLY STREEETFINDER FOR PALM V
I just got a Palm Vx so I'm planning to get the Rand McNally Streetfinder for Palm V and get rid of the laptop and GPS in the car.
GOOD
- This should be a much smaller, portable solution with less wires. This GPS attaches to back of the Palm V. Small size and battery power will mean that I can take it hiking or mountain biking.
- Plus it comes with a windshield mount, so it could be placed in a better field of view (as opposed to on the passenger seat or car console).
BAD
- The maps will be in black and white (ever tried to use a map that was from a photocopy?).
- There will be less use for door-to-door navigation, but I use my GPS more for the moving map function to see how far I've travelled and where I am relative to other routes.
- I've read that the maps that come from RandMcNally take alot of room on the Palm V, but the QuoVadis program by Marcosoft sounds like a good alternate Palm GPS program.
GARMIN STREETPILOT COLOR MAP
$611 at computers4sure.. but with 20% brands4less discount, $489.
GOOD
- self contained GPS unit with moving maps
- car mountable, color maps
BAD
- small screen size (compared to Palm V)
- need to purchase additional CDROM and data cartridge to use additional maps
Rand McNally has had a 20% discount on your first purchase when you register at their travel store. GPS for Palm V is $169 - 20% = $135 + $18 shipping. However, probably be better to use one of the other currently available deals at buy.com or computers4sure.com
