I don't know if the 710 works with e53. The 710 but for the fact it has wifi to do updates itself is worth the price itself.

It insists on doing a full scan of modules before you can ignore the 90% and go to the one module you want so for basic scans I use BimmerLink. BL doesn't work on e53 though I'm pretty sure
