I have a Garmin 760 and have found many great poi's but how many is too much? If you add too many will it make the garmin sluggish?
I have a couple thousand POIs and I have not noticed any lag from them.
The only thing affected by the number of POI is the time to search for one by name. At least that has been my experience. But as the unit comes standard with several million POI installed by the factory, adding another million or two custom POI isn't going to affect that much.
The only limitation I appear to have on my Nuvi 350 is the total number of custom POI's it wants to display, however, it is not sluggish.
good question I was wondering the same thing myself
I am running about 100,000 on my 760 and c580. It takes about 3 to 10 seconds to display the list of custom pois. The key is to wait after you have touched the screen. It will come shortly.
I currently have over 340k on my 750 with no problems. There is a brief delay for larger POIs (like Walmart) to display, but it's within my tolerance.
about 60,000 POIs on my Nuvi 200 and I haven't seen any sluggishness.
I don't experience any lag time
I find that if I put too many large POI files in my Extras it can take a very long time to search. Some of the large USA store files like Walmart do seem to slow all my searches. I have begun to just add the large POI files as I need them for trips.
The size of the POI files seems to have no effect on the general map navigation function or display.
I found that if POI's are in seperate folders it takes 30 seconds to load when searching through them.
also when i had all my poi's loaded on my unit i seemed to apear to have a lag in my map updateing. I since loaded my POI's on a memory card, only putting it in when i need it.
dont know if this was related to a bad firmware or not.
I found keeping POIs on SD card making my Nuvi 760's screen refresh very slow. I transferred them on the unit and it appears to be better.
