I followed the instructions, but do not have 3 files, and I have a file that is not in your garmin folder.

I do not have the gmapsupp.gma, gmapsupp.unl, and the 0464H4AO.pnx files

I have an extra sid file, D3157110A.sid (instasearch)

Anyone know where I can get the missing files and/or are they needed to perform the update.

Thank you.
