I agree with x-trail and Neil.

I completely understand Garmin wanting to protect their own investment in mapping products. However, should they prevent future use of third party mapping solutions (I like to use/make my own), I will never buy another Garmin product.

I hope Garmin realize one of the largest contributing factors to their success in the market is the sheer number of freely available third party mapping solutions available. Should they lock their devices to use only official Garmin maps, they will no longer have any advantage for me over competing units.

I have loaded two Oregon 6x0 units with 3.70, one was bricked, and the other repeatedly locks up/crashes less than an hour after boot, with only the original Garmin maps installed.

Hopefully, Garmin will respond quickly with a 'patch' for their 'patch', a theme that has become all to common in recent years with Garmin software engineers.
