Nuvi 2689 white screen coming out of standby

 

Occasionally my Nuvi 2689 wakes up from standby with nothing but a white screen. What I usually have to do is then fully power down by holding the power button in for about 10 seconds, and then power back up. This essentially causes a reboot.

Anyone encounter this or have a remedy. The unit has had maps and software upgraded several times and the issue still occurs.
