Welcome to Fixya.

This is a known issue for Garmin nuvi 550 and 650.
Re-calibrate your touchscreen.
Press and hold the power button 2-3 minutes, the unit will enter the calibration process. Calibrate as instructed.

Thank you for using Fixya, have a great day.

You can use a USB Flash drive or SD/MMC Card or an iPod to view files (Pictures,Videos,Music files..etc) in the player.Touch the icons [USB], [SD CARD], [IPOD] according to which device you are using.The corresponding modes are switched automatically by the player when it detects one of the above devices.The player will switch to [RADIO] mode automatically when the above devices are disconnected and if there is no Disc in the player or to the [DVD] mode if there is a Disc inserted.You can view the detailed description in the following link ( http://www.poweracoustik.com/pa2006/manual%20and%20catalog/source/PTID-7002NR.pdf ).Your valuable feedback would be appreciated.Good Luck.

You need to upload then via USB. You should have a cable that came with your unit

Sounds like you need to recalibrate the screen. This can be done by following the steps below:

To Calibrate the Touch Screen on a zūmo®:
1. Turn the unit Off and make sure it is not attached to any outside power source.
2. Power the unit On, continue to hold the Power button for 1 minute. 3. A screen will display that says, Press dot in the lower left corner. 4. Release the Power button and touch the sequence of dots until your unit says Calibration complete.

Good luck!

You need to calibrate the touch screen. With the unit off press and hold the power button until the calibration screen appears (approx 35 seconds). The follow the instruction on touching the dot on the screen. Once this is done your screen should be OK.

Try to calibrate the touch screen. Push and hold the power button on until you see a white dot on the screen. This is the calibration mode. Touch the dot and another dot will apppear, now touch this dot again, keep doing this until the unit reboot.

If you touch the 1st dot and nothing happens then the digitizer on the LCD is dead. If the unit is still under warranty, get a RMA and return it to Garmin.
