Have a couple questions about my Nuvi 2598 LMT-HD:
1) I have been unable to find where I can disable auto zoom, I like my zoom at 500ft or 800ft, but whenever I switch screens shut off and turn back on it goes to 0.2mi or more. Is there such a setting?

2) The new On/Off feature. I liked the old way of just pressing on/off button for 1-2 seconds to shut off, now that only puts it into sleep mode, now I must hold button for at least 5 seconds (seems like forever) for it to shutdown, otherwise battery goes dead. Can this be changed via setting or software hack?

Thanks in advance for any help on these.
