Is it possible to upgrade my 2010 rx450 mirrors to add automatic folding and blind spot warning? Want to keep the car but would love those features. Thanks

 

There are several "after market" blind spot monitoring systems available. Just do a google search for them.

 

I asked my Lexus dealer if this could be done on our 2010 and the answer was no. We have since bought a 2015 and this is one of the major reasons for the the purchase. I would find it uncomfortable to now drive without blind spot monitoring. The folding mirrors in my opinion are not that beneficial.
