Adding Blind Spot Monitoring and Cross Traffic Alert?

I’ve searched the forum but haven’t found any answers, apologies if this thread already exists.

I’m wondering if it is possible to add the features of the ‘Tech Package’ later on if you’ve purchased a truck without?

I’ve got an ‘18 Canadian TRD Off Road, so I already have the heated seats, power rear window, dual climate and color-keyed bumper.

Specifically I’m interested in adding the Blind Spot Monitoring and Rear Cross-Traffic alert.

Is this possible?

 

It’s possible but not likely if cost is a factor in your decision to proceed...
