I managed to download and install the new version on my 8310 last evening and found that now the Drive To menu option from my Contacts folder no longer works. When you select it from your Contacts menu it loads Telenav but the program freezes on the main menu. I have contacted Telenav support but have not had any reply yet. If you use this feature, I would suggest staying with your current version. I wish I had. (If anyone has access to the 5.1 .jad file I would appreciate a copy to revert back and wait for Telenav technical to figure this one out...)

UPDATE: I have found that the real issue is that MS Outlook uses "United States of America" as the default country code in Contacts. Telenav "Drive To" and "Map It" features from Contacts menu will work fine with contacts using nothing or "United States" or "USA" but NOT "United States of America." I do not believe this was the case with the prior version. If your contacts do not have "United States of America" in the address, you should be fine with the new release. Hopefully, Telenav tech gurus can fix this for those of us using Outlook.
