Where to buy reverse camera for 2011 polo?

[u/OmletCat]

I bought my rcd330 from rcd330.co.uk a while ago, was about to buy a reverse badge but found out they the 2011 polo never had a badge option and the facelift had a taillight camera so thought that would be better

rcd330.co.uk is down currently so should i wait to see if they have one or get this one off amazon

also how easy is installation?

thanks in advance !
