Purion 200 or 400 ?

[Andy.M]

Got Bosch smart system on my new bike and it only has the LED remote. I know I can access all the info on my phone after a ride but don't want to strap my £500+ phone to the handlebar for in-ride visuals.
Not sure between replacing the LED remote with the Purion 200 or keeping the remote and adding a Purion 400.
Any thoughts to advantages/disadvantages with either unit?

Take a look at this thread, pretty much the same question.

I did see that late last night but saw Kiox and my tired brain must of rejected it as viable information!
That thread is v helpful to my question.
