I've read somewhere long ago, the problem is in the USB. My guess is, the 2.0 can't support the data transfer required to run things smoothly (Just a guess).

These were all speculations at the time and perhaps wrong info from r-link customer helpline people.

The specs are definitely very similar in both units and can't forget that android has been activated on older r-link 1 units.

The USB 3.0 standard was launched in 2008 but is still something unknown for Renault?!?

There are 2 important differences: 

1. Speed. USB 2.0 has 480 Mbps and 3.0 has 4.8 Gbps (the maps for the whole Europe are a little less than 1 GB)

2. Power. USB 2.0 up to 500 mA and 3.0 up to 900 mA. So, USB 2.0 with a current of 500 mA has limitations when charging a larger smartphone or tablet battery. 

I don't believe Renault when they say that the problem is USB version. Like I don't believe them when they say they cannot retrofit walk-away lock.

To be honest, a lot of laptop manufacturers also has same problem. Not to mention phone manufactures... say, which android phone works on full USB3 speed when connected to PC? We know that iPhone does not... I beleive that magic word is 'not need' and 'compatibility'. To charge newer phone or tablet you need at least 1A on USB output. With 500mA good luck... and for charging you do not need USB3. Powered USB2 is enough.

It is a difference between charging and keeping charged. When I am using mirroring function the amount of energy taken from USB must be at least equal with the one consumed by the phone.

I am sure that "if there is a will, there is a way". Renault is just not interested to solve this and somehow I understand them - just read their last year selling results!!
