Recently after uploading several large POI files to my TomTom Pro 7150, it started to freeze up every time I tried to "edit" the POI file (like putting an audible warning on the POI for example). I guessed, and guessed correctly, that the huge POI files (containing over 8000 entries) were just too much for the unit to handle, memory-wise.
So I split some of the larger POI files, then uploaded them to the GPS, and the problem went away. No more freezing when I clicked on the POI's.
I'm guessing that this is not specific to TomTom. So if you run into problems with your GPS freezing up, try splitting the larger POI's and see if that doesn't fix the problem.
Vito, I don't think Garmins would have this problem. For instance, the Offbeat Tourist Attractions POI from Bobkz has over 18,000 entries and doesn't cause problems. Try loading that one into your Tom Tom and see if you get the same results.
All 3 of my nuvi's have about 70,000 custom POI's. All of the POIs have custom icons and about half have audio alerts. The only problem I have ever had is if I get too agressive with the "tour guide" alerts (too large a radius causing frequent multiple alerts as you navigate). This can cause the nuvi to lock up or spontaneously reboot, especially on my nuvi 855. I have changed most of my alerts to proximity rather than TourGuide and set reasonable distances, and have no problems at all. So in general, I agree with plunder. The Garmin devices can handle tens of thousands of custom POI's with no problem.
report it as a bug
have a heap of car tomtoms, some poi groups have 80K entries no trouble displaying editing them
could be some simple change to the nav core
Yes, I had that one loaded into my TomTom and I didn't seem to have any problem with it. This is a really curious problem. But as soon as I split two very large files (Truck Stops and Rest Areas) and re-uploaded, the freezing went away. And the problem wasn't just once. It happened many times over the course of 2 days before I finally split the files.
I've seen the spontaneous rebooting as well. Thanks for the tip, I'll make sure my proximity settings are not set too closely together.
Well, I did. I talked to Tech Support about it. The tech thought that was I was seeing was indeed attributable to the very large POI's.

I would not place a lot of faith in that response if you mentioned it first. In my experience, if someone in product support at any company has no idea how to solve a problem, he/she will jump at a suggestion from the customer that lets him/her close out the issue with no more work by the support person on the call.

I agree 100% with your statement. A lot of customer service or technical support people will take the easy way out and just agree with what you suggested. Not all, of course, but a lot.
can't believe the answer if you told them any part of your impression
It just means the tech doesn't have to think
I have many POI with more than 80K points

Keep radius tight or unit is always alerting.
