Ok so I have the old Navman Sleeve and love it... however the connection is ok but does drop every now and then. This weekend going to Dave and Busters in Philadelphia it disconnected while in the city... so I just pulled out our trusty maps.google.com printout that I brought just in case....

well here is my question..

Does anyone know how I can open this sleeve up and add an external antennea like in the new navman sleeves? Has anyone done this? if so where is there a walkthrough...

As a test today I did this..
car in garage has 0 of 11 satellites
car driving to work had 3-6 of 11 satellites (clear day so this was good)

my other gps solution is the older cf globalsat with external globalsat at-65 antennea
car in garage has 8 of 11 satellites
car driving to work had 8-10 satellites

my globalsat wasnt worth a darn before I bought the external antennea for it but now is solid but slow....

so the trusty old cf card has better reception but differences...


Globalsat 307 CF Card............................Navman Sleeve
4800 baud............................................56 ,700 baud
CF in dual sleeve jacket (bulky)................It is its own sleeve and not so thick
Internal Extended Battery.........................No internal battery

so they both have their plus and minuses but I may just have to buy a new navman sleeve to get the external antennea ability.....
