My question was simple. I know that I have to go online for the program to delete old geocaches that I have downloaded onto my Garmin nuvi 550. I do not know what the website is to do that. Secondly I accidently deleted some files that were vital to the 550. Do I need to send the unit to someone for reinstall of those files or is it something that can be done on the internet? I have asked you those two questions twice already. You have not sent me an answer. Send answer via email!
No, the Nuvi 550 will not boot up. The only time it comes on is when it is hooked to the USB port and then it reads " vital files missing".
