OK, I got the Rand-McNally Streetfinder Deluxe 2000 (from the Office Depot GPS closeout) onto the CF-01.
I used a PCMCIA Zip SCSI adapter, connected to an external Plextor Drive (plug-n-play in Windows 95b), and followed the standard installation procedure. Then I chose 'Install Local Maps' from the File menu to copy the map database onto the hard disk. This was a pain, since it kept asking me to switch between Disk 1 (Western US) and Disk 2 (Eastern US) as it processed the states in alphabetical order. There's not enough space on the stock 1.6 G drive for the entire map of the US - so you have to pick the ones you want, which is not a problem. I pushed my luck a little, and decided to DriveSpace the drive to free up some space - big mistake! Anyway, to cut a long story short, I was able to recover the drive (I think), by a combination of going to safe mode, running scandisk, and so on. Not recommended - the better alternative is to use a larger drive.
Anyway, now it's got the Streetfinder with enough space for all the US maps. I haven't tried the GPS yet, but it should be a piece of cake. I'll hook up a custom lighter jack cable for both the CF-01 and GPS later. The CF-01 alone can be used for address location, etc., and fits easily in the glove compartment.
BTW, Micro Center in Santa Clara is having a closeout of the Streetfinder Deluxe 1999 (software only) for $2.99 each. I haven't tested that one, but the only differences will be the slightly older maps, and the business guides (some new restaurants, etc.; and maybe some older restaurants, etc. did not renew this year).
