Topdon AD900 Lite Bundle Renewal vs 30 Special Functions Bundle

Question: 

What’s the difference between the Topdon Artidiag900 Lite bundle renewal and AD900 Lite 30 special function bundle in the picture? My current software doesn’t run out until August of this year. If I buy the bundle, will it come into effect immediately or when my current software ends?

Solution:

The two options are different:

AD900 Lite bundle renewal:  The 1-Year Renewal Bundle extends your AD900 Lite software subscription. Since your current subscription is valid until August, the additional year will begin after your current subscription expires.
The 30 Special Functions Activation Package is a one-year activation that unlocks the additional special functions on your device. AD900 lite comes with only 8 service functions by default.
