I had one before I traded it in for an HDS 7 Touchscreen. No reason to take it out, it is fine in the unit. I'd probably lose it if I took it in and out. It uses the micro chip which is really tiny. The Elite 7 had a problem with response time when using the Navionics chip, not sure about yours. Their last update to the Elite 7 was supposed to fix that issue. If I had not had the problem early on I would still have it. It was a great unit otherwise and super sharp images.
If you experience any response issues with the chip, PM me, I may can save you some headaches.
