recomend sat nav program

Hi all ive been given two android tablets to mend for which ive sorted
one is a google nexus7 1st gen second one is bitmore tablet
anyone recomend a gps program to use on either of these
tomtom. Sygic. Primo etc
i was hoping to transfer the primo i use on a chinese wince6 device
until i relised it wont work on android
also ive tried to d/load sygic different version but it lead to dead links

So what you guys use on 7" android tablet
and uk only
thanks

just an update

after spending many hours of search and d/loading (lots of dead links)
ive found this iGO_Israel_9.6.29.390522_crk_sys_changed

loaded onto the bitmore tablet then found out it had no gps in the tablet
so i loaded it onto the nexus 7
when it on potrait screen primo looks normal see all button and features
but when i turn it to landscape the buttons and feature buttons are lost beneath the screen
and it dont fill the righthand side screen
so i edited the sys.text
this is before the edit
[rawdisplay]
force_renderer="RENDER_MOYA"
;highres=1 ; for full HD
;driver="gdi"
;driver="engine"
screen_xy="auto"

and this is after the edit

[rawdisplay]
;;;Nexus7
;screen_xy="1280x800:800x1280/1280x736:fullscreen"
force_renderer="RENDER_MOYA"
;highres=1 ; for full HD
;driver="gdi"
;driver="engine"
screen_xy="auto"



is this correct setting,according to google the display on the nexus 7 is 1280x800
and i got screen info app which says
landscape mode 1280x736
potrait mode 1280x800

The semicolon (this is the ";") in front of the line gives the line a comment or simple text status. It's no command (to use screen resolution) anymore

;screen_xy="1280x800:800x1280/1280x736:fullscreen"

After delete :

screen_xy="1280x800:800x1280/1280x736:fullscreen"

just an update

ive edit the sys.txt and took the (;) out started igo it was still the same
so i edited the the ini file within the config zip and deleted the save folder
and started primo again and bingo the screen is what it should be in landscape mode
and potrait mode
just gotta get the tts working on it then il be happy
i gotta find a post by chas (i think) or yurblytuglly about getting tts to work

thanks agian to katastrofe for the little mistake i made
