- If your Garmin Nuvi 350 is not responding to taps on the touch screen application, recalibrate the screen. To do so, touch "Display," then touch the "Recalibrate" button and follow the on-screen instructions.
- If this previous step does not solve your issue, visit the outlet from which you purchased the Garmin Nuvi 350, or contact Garmin directly by going to Garmin.com and visiting the Customer Support page. You can receive support via e-mail or phone.
