Some units only work with some providers.
Garmin unit has no sim, can be hard wired and also importantly not only texts but emails any number of addresses. MOST importantly it texts and emails when turned off or disconnected from power source!
Plus it's a retail unit that is far superior to all the others in useability terms!!!!
Paul...I've seriously looked at the Garmin device and I'm sure it's brilliant but, in the end, like with most things, price has to be a consideration. I'd like a Redbay, but...
I've had my Xenun tracker now four years: total cost £40 for the tracker, £5 the hard wire lead, £5 postage, £2.49 iPhone App, O2 SIM top up £20...total cost £72.49. Sweet.
Just to clarify a couple of things from my own experience:
* If I didn't plan on asking my boat where it was anytime in 3-6 months then I'd have been thinking I didn't need a tracker or it'd been a waste of money.
* My (O2) tracker SIM has voicemail switched on. If it's a problem, I've not noticed it.
* From reading the forums the real deal Xenun tracker works with any UK mobile provider (why shouldn't it - it's a industry standard protocol). I've read that some clones don't but that's just hearsay.
* The Xenun tracker - and the clones for that matter - can all be hard wired.
* The Xenun TK102 doesn't have a disconnect/turn off warning. The Xenun TK103-2
at $103 does however as well as notification for engine start, low oil level and other stuff.
Not sure what you mean by the Garmin being a "retail unit" and "it's far superior to all the others in usability terms".
