I’ve been testing the OBDLink MX+ ($99.99) from Scantool.net, which uses a wireless dongle to connect your car to your smartphone, tablet or Windows PC via Bluetooth.

The OBDLink MX+ is a $70 car diagnostics tool that pairs to your phone via Bluetooth. By providing data on issues, it could save you a lot of money in repairs.

Make the connection and then launch the app and you’ll see the main screen, where you’ll still need to touch the “connect” button.
