Garmin offers this in a number of products.
What would like to be done in using Streetmap Premium with custom roads is to be able to add POI's with a buffer voice alarm alerting the user that they are approaching the specified POI. Our line of thinking is to identify high risk intersections and give a 30 second warning that the driver is approaching one of these intersections (in order to raise their level of alertness).
Hi Eric Collins,
Could you tell me please if you were able to find a solution? This capability is very important for traveling securely.
Thank you,
Rafael Casagrande
No - no solutions have been proposed. Navigator apparently does not have this functionality and there is no information as to whether or not it is being considered.
