Quest 2 CN Europe NT v9 - opinions sought

My Quest antenna failed last week so it was returned for repairs (£74) Three days later a factory refurbished Quest 2 arrives with a note that Quests are out of stock at the moment. A quick phone call determines that a "new" batch of Quests are due in next month from Taiwan and I can do a swop if I wish

I have been more than happy with my Quest and would not normally "upgrade" after some of it's successor's scare stories - however I wonder how the CN Europe NT v9 runs with system software v 3.10?

Assuming that Garmin will give me a free unlock for the mapping I could be tempted to keep the machine, especially if I can run the full PGPS camera database rather than just the overlay

Anyone have any thoughts or experience?

I guess I could also delay registration until v10 appears for a free upgrade

Many thanks

The latest version mapping has outgrown the Quest 2 memory capacity, so you cannot fit the whole disk on, you now have to be more selective. john
