Just purchased 19 CPO RX350 with Nav and Premium etc

Some technology questions if u can help

a) Is there an option to see current speed digitally anywhere?? (i do not have fully electronic dash)
wondering is its an option somewhere in the info display in the center of the dash

b) Is there anyway to display digital time on the NAV screen??. i have analog clock obviously in the dash and digital time on the info display on the dash but wondering if it can display digital time on the giant nav screen...anyway to add it in the set up?

c) the car is not eligible for Android Auto/Apple Carplay so tech upgrade/refresh from dealer is not an option. Wondering if any Android users have a trick to allow TEXT messges on the NAV but not EMAIL. on the settings on the phone on android(galaxy) i can only toggle on and off a generic "messages" which seems to control both TEXT and EMAIL on or turns them both off. I would like to get TEXTS but not all the bs emails that hit my phone? anyone know if tghere is a way???

Thanks in advance for any and all help that can be provided to a new , first time lexus owner
