Most of the LDS's won't do the replacement for you because of the perpensity of leaks and having to bite the cost of repair/replacement. Best bet is to send it in to Suunto to have it done. If they mess it up, you get a new computer. Happened with my husband's Stinger. Sent it back for a battery replacement, it came back even more dorked up, so Aqualung sent it to Suunto for real repair. I'd rather be without it for a few weeks and have it done properly with the opprotunity to get it replaced free, then to argue over it with an upset LDS that really tried their best to help the customer out.
