I Got my TT5 working on the K-Jam! (Partially) This is what I did:
1 - TT5 did not istall properly over active sync - So I installed all of the CAB filed to my Storage Card and installed directly on the divice (I belive there are 4 files + get 1 voice file by searching the CD) I belive some the files are named ttn, GPS, etc)
2 - I emailed TomTom support and sent them a copy of my card so they can allow me to Re-activate my account (Belive they needed a copy of the card/cd, invoice of purchase and device invoice -- u can scan them , attached them, to a word file and email it to them). My code originally activated for my JAM (diff device code).
3 - I used the TomTom Map software to install the map to my PC. Then I copied the folder to my devices card via active sync
4 - when I started the TT5 -- it asked me for the activation code (which I got through ttcode.com)
5 - I activate the GPS control panel on Windows 5.0 (instructions I found on this site)
That is as far as I have gotten -- I am trying to figure out how to LINK the GPS to the K-Jam -- TomTom only lists a few coms open, but not one that the Blue Tooth lists.
Once I Figure it out -- I will post again!
Email me if you have any questions.
Hoped this helped!
