@Benstevens: I've had a look into this for you, and these 2 models have almost identical specs, with the only differences being that Mobile Tap Mirroring and Sound Mirroring are available on the TU7100, which is Titan Grey, while the TU7020 is Black and does not support these features. You also get a better energy Efficiency rating on the TU7100, with an A+ rating vs an A rating on the TU7020. I hope this helps.
