About to switch from my Apache to Titan. Need some advice/reviews/suggestions

[BooDaddy]

Hello all.
I am a fairly happy Verizon XV6700 (Apache) user and I have used the apache forums for quite a while now.

I am considering switching over to a xv6800 (titan). I like the built in GPS.

I have a question. How accurate is the builtin gps? I am currently using a Holux M1200 bluetooth reciever for my GPS on my 6700. Would the titans built-in gps be as accurate as the Holux?

I mainly use 2 programs for GPS mapping.... Garmin Mobile XT (on road navi), and Back Country Navigator (geocaching and offroad navi). Would the titans built in GPS work with these apps?

Also, please if you have any reviews or suggestion for someone about to make the upgrade from an Apache to a Titan, please let me know!

Thanks!
