As I Realtor i use navigation multiple times as a day and some days as many as 10 to 15 times.
using my phone or a dash mounted GPS didnt appeal to me so I began on my search for a solid aftermarket install for my 2015 RX 350. I am happy to say I am very satisfied with my selection ...check out the LGVIF-CB2W Wireless S-Connect Interface for Select 2013-2021 Lexus Models from Beat Sonic USA.

NAVIGATION INTEGRATION IS FANTASTIC as is the other features, google voice search and youtube music and the device integrates perfectly into your sound system . A user friendly software and the hardware is all installed under the dash and console ( not in your glove box) the only feature i dont have immediate access to are the temperature settings ..
The onboard display replaces your current display perfectly.

purchase price is $749.00 .... great you tube videos are availble for installation and Beat-Sonic dooes have authorized Dealers who will install the device.

Works perfectly for Andoid and Apple

I am happy to say I made a great choice.
