Nuvi 550 Disassembly

[Loopie]

Any chance anyone knows how to disassemble a Nuvi 550. I need to replace the digitizer. I pried on the front face a little and didn't like the sound I was hearing

Here are some notes I found on the net for Nuvi 500 disassembly, please note I have not done this myself so I can't say if it is correct :-

1. Remove battery (if installed) from back.
2. Pry off front face (small flat head screwdriver)
3. Remove screen (front) from back panel (8 torx screws)
