GO 5000 - No Maps Available

Hello all! Newbie here - I have a question about my GO 5000, which somehow deleted my maps, and is now caught up in a 'no maps found' loop. I cannot get past the 'No maps' message, which means I cannot format a memory card to allow a large map update, therefore cannot add a map etc. etc.
I understand from browsing that a small, or 'keeper' map can be installed allowing the card to be formatted; please could someone help me out as to how to request this? I have the lifetime map updates services. I have recently purchased a new Tomtom, but would really love to get this one back on the road too (no pun intended!)
Thank you in advance.
