I need to reinstall the software on this RouteFinder, What brand and model number of CD Rom drive does this require, do you have them for sale?

You do not need to buy a special CD-ROM drive. You can use a standard 40pin CD-ROM drive to reinstall the software. Please open the cover and check to see if there is an adapter on the hard drive cable which allow you to connect a standard 40 pin CD-ROM drive. If you do not see the adapter on the hard drive cable, we can send out an adapter to you, please email us your full mailing address to tsupport@multitech.com .

Here is a document that shows how to reinstall the software:
