Oregon 550t

[+Prime Suspect]

Your message was lost.

 

The only report on this I've read said it has a SiRFIII chipset. I've not seen that confirmed anywhere else.

In my OP, I just asked if anyone had seen or heard anything official about which chipset ( brand and model) would be in the 550t.

 

PS,

I sure hope you are correct ! ........because, if you are, then most of the remaining Oregon "problems" would just quietly go away.

SirfIII???

 

I'd like that very much BUT I doubt that report is true considering that even in the 60CSX they are switching from the SirfIII to Mediatek's latest offering. I would think that our only hope for a better chipset would be in the new chips from Mediatek.

 

So far, in my Oregon I'm very dissapointed in the Cartesio. Going down the road in your car it's very accurate, you can even see lane changes. At hiking/walking speeds the Cartesio turns into Mr Hyde and gets nasty, especially if you challenge it with trees or hilly terrain.

I seriously doubt you'll see SirfIII show up in any new Garmin receivers.

 

My guess (in order of priority):

 

STM Cartesio (no change from OR300/400)

MediaTek 3329

SirfIII

According to MediaTek:

 

"The MediaTek MT3329 single-chip baseband features -165dBm ultra-high sensitivity with least power consumption of competitive solutions, also the fastest acquisition on the market, designed for mobile navigation devices where rapid time-to-first-fix (TTFF) and superior navigation performance are required. Besides, the MediaTek MT3329 enables the most precise positioning even under slow movements like hiking or mountain climbing, which is ideal for Garmin’s outdoor navigators."

 

I'm very hopeful about the specs. At least they've put emphasis on the "...precise positioning even under slow movements...". That tells me the industry recognizes the problem with earlier Mediatek and the current STM Cartesio with their slow movement deficiencies.

 

I'll hold out a few months or even a year for the next generation of Garmin handhelds that have this chip. The Cartesio leaves alot to be desired.

Given that they are advertising HotFix on the 550t (I just noticed this today) I'm betting heavily that they haven't changed anything since I believe HotFix is specific to the STM chipset.
