    No it won't work using the methods described here as you've read. They are dissimilar hardware. There are only 3 Garmin car to truckie's navigator conversions possible that i know of:

    nuvi 2x5W > nuvi 465 [HWID 0827 only]
    nuvi 2460 > dezl 560
    nuvi 2797/8 > dezl 760/RV 760

    The key is matching PCB P/N of the units. If they don't match then simple firmware flash won't work and if you force a flash the unit may brick. [Only registered and activated users can see links. ].

    I want to convert 2797 HWID 1517 to DEZL 760, is it the same procedure?

    Some of the links in your thread was dead but I downloaded:


    Code:
    Please Login or Register to see the links
    Then save the boot.bin of nuvi27x7and27x8_GCDFile__450.gcd
    Load dezl760_GCDfile__470.gcd and load the boot.bin
    Override HWID to 1517 and save it as dezl760_470.rgn

    Then do:

    Code:
    Please Login or Register to see the links
    Just want to be sure so I don't end up with a bricked device.
    Also, will I still receive free lifetime map updates after converting it?

    Yes the procedure is exactly the same, just substituting the relevant firmware boot and fw_all bin components from nuvi 2797 and dezl 760 as you've described above which is the safest method of course. It would be even safer to save the RGN file as 151701000470.rgn before flashing with Updater.exe. Complete conversion should also be possible to dezl HWID 1516 however that's intrinsically less safe, and be aware i don't have a 2797 available so i'm unable to test either method beforehand. BTW, none of the internal links in post #1 for backup nonvol, RGN_Tool or Updater.exe are 'dead'. Also they can be found via our Indices in any case as can the links for all current firmwares be found in the [Only registered and activated users can see links. ].

    Please keep in mind that although this should be without problem, any risk is by necessity taken solely by you. Please report back the results if you proceed with the conversion. I'd be particularly interested if the BC20 backup camera works if you intend using one. It may be locked out from 2797 by either firmware or differing pinouts, or it just may be that Garmin wants ppl to think that it doesn't work with 2797.

    Because the Lifetime Maps subscription is tied to the Unit's ID number which doesn't change, you will continue to receive them and the ancillary files as usual even if the unit's HWID were to change on full conversion. Just in case you missed the notes at the base of Method 1 in the initial post, be aware that if you update software by GE or WU then it will download any new unit firmware for the current HWID so if that's the nuvi's HWID of 1517 the unit will be reconverted back to a 2797.

    I have successfully converted it to dezl now. Have no camera. I think I will keep it this way and not try to do a full conversion and risk damaging the unit. I guess there is no reason to do a full conversion?

    The only reason to do a full conversion [other than the convenience of updating firmware as detailed in the last para of my previous reply] is in case the original fw boot.bin was not capable of initiating and loading the dezl fw. This can be seen in the case of conversion of [Only registered and activated users can see links. ] where the smaller 3790 boot cannot handle the 3490's bigger [than 3790's] fw_all component and so the conversion is done using the complete 3490 fw. So that the inadequate boot bin can work, there is a method of compressing the donor firmware developed by our resident genius kunix using his [Only registered and activated users can see links. ] but if you want to understand the background reasons for packing in that case read the posts before and after that link. Although it's simply academic for conversion of nuvi 2797/8>dezl760 or RV760 because the nuvi's native boot bin works with the 760's fw_all bin uncompressed anyway, not all fw can be successfully compressing using the gfwpack.exe tool.

    In short, because the 'safest' option method of hybrid fw works without any compression of the donor fw to convert 2797/8 to 760 there is no reason at all to think that the full conversion would not work successfully exactly as it does for nuvi 2460 to dezl 560. If the unit was mine i would now happily do a full conversion. My 2460 has been converted back and forth to 560 many times using both methods [always with nonvol cleared] and is still kicking. But as always the risk if any is yours totally.

    If you should ever get access to a BC20 i'd be very interested to hear if it works with original 2797 and/or 760 convert.
