Nice pictures, but please repost them and make them smaller. Forum rules call for pictures no larger than 640x480 (see - http://www.gpspassion.com/forumsen/topic.asp?TOPIC_ID=12223 ).
Thanks. |

Nice work, I had messed up the screw when I tried to open mine.
Same problem as on the GPS10x, you can't access the GPS chips under the antenna. Did you try prying it up gently, sometimes the cache is just tightly fitted.
With that SiRF logo and general behaviour of the GPS, there's really little doubt that it uses the SiRFstarIII chipset, likely the same IIIlt version as on the GPS10x, hence the better battery life than on the TomTom ONE. I'll see if I can get some type of "offline" confirmation when I roam around the Bay Area in a couple of weeks ;-)

That sure does look like a battery that is relatively easy to replace - much like the first gen iPods which were a breeze (and unlike the new iPhone which looks like a suicide mission - leads soldered to the motherboard).

Thanks for the excellent pix.
There's more than one part to the battery life equation. You've compared the "in" side: mah rating. But then there's the "out," which may be much higher demand in the TT for all I know?

Argh... the "out"!
No wonder I returned TT1 after less than a week!!!! ( I was charged w/ 15% restocking fee - well worth it!! ) How can they call it "portable" if can't even last couple hours?

Thanks for the pics! I don't know how many of us are brave enough to take it apart!
Different design and different components will dictate different current draw. Is the LCD display the same (manufacturer) on both units? This is the major source of current consumption. |

I didn't notice about the manufacture id on the screen of TomTom.
But one thing for sure, you will NOT be able to see TT1's screen just the sunny day. (not even direct sunshine, let along open my sun roof when using TT1 )
On the other hand, I will buy TT1 for NO MORE than $75. (well, I will buy it just because it has map of Canada) If more than that, I might as well buy the NA from Garmin.  |

| Nice teardown! The chip with the "OMAP" silkscreen is the main microprocessor. TI, which owns the OMAP processor family, designs customized processors for/with Garmin. Just Google "Garmin OMAP." The other part next to the antenna with Samsung marking is the NAND Flash memory. I can't read the part number completely, but it appears to be an 8Gbit (2GB) part. Notice how the have a pad next to it where another part can be populated. |

Thanks for being so brave to open it up and sharing the pictures with all of us!
With the antenna position where it is, I wonder how the GPS signal get in when the unit is lying flat on the floor? Perhaps the screen they use is of a material that can allow the signals to go right through without much attenuation?
By the way, can you please clarify your statement - "...The antenna place 90 degree to the floor and it is about 2X larger than the TomTom One - place parallel to the floor..."?
Thanks! |

Nice breakdown and circuit map of a StreetPilot i3 here:

May help identify circuit components on the Nuvi. |

| no clue, thx for the hi-res. Yep, Garmin is Sammy all the way for NAND & SDRAM. The NAND is 8Gbit & the smaller chip is the 256Mbit (32MB) SDRAM. The preceding "K" identifies it as a Samsung memory part. |

I'm afraid to ask: Did you put it back together and does it still work?
