I used this vendor because he had a great Ebay rating and many others here were very satisfied with their purchase from this source.

You will only need the connector that comes with the software. Many of us have dedicated a Windows XP based laptop to the software because the software requires quite a bit of disk space and it is more convenient to do so.

If you go this route the software will load automatically and if it doesn't there are several here that can help you through the process. I have found the seller to be helpful and responsive.

There are also apps that connect wirelessly to your phone that will give you info on the go. You need a wireless connector to do so.
