Garmin 96C problems

Has any one out there had or heard of problems with the Garmin 96C GPS. I am on my fourth one and now it has locked up after only a few times of use. Lucky for me I have not been out on a long cross country with it when this has happened.

Any feedback?

I'm looking at one of these and noticed this post. Any other feedback? I have a 496 and I'm thinking of "downgrading". I don't use the XM weather or radio and don't use the unit that often in general.

Thanks.
