Something I have found useful is this
Garmin GPS
you can install an AP on your smart phone so it bonds with it to receive traffic & weather alerts plus it can be your speakerphone with access to your contact list (it acts like a pass through)
or pay 80.00 and get the digital antenna / power plug so it does just the traffic & weather only.
Using the Garmin software (free) on your PC you can program locations and when you invoke a trip it looks for traffic along the way. Or you can ask it to show you traffic as it is voice activated.
Easy to mount as you can get a weighted bag mount so it just sits on your dash making it easy to remove & move to a different vehicle.
Lived in Houston all my life and seen traffic patterns change so bad I hardly ever go out
