garmin 1490-t have a very impressive list of feature , but they relibility fall far short from the advertisement . Bluetooth : work about 75 % of the time . traffic report : totally inaccurate . Lane assist : work in about 50 % of the time you need it to work -lrb- could be that we highway in Dallas be too confusing for Garmin -rrb- . I be sell mine on eBay and go with another brand . I hope you experience be better than mine .
