There may be issues with the CAN BUS thingies when retro fitting the radio to a mk5 causing battery drain. I used to know all this stuff but have forgotten it all now.
All I can remember is that on some mk5s (including both the ones I had) that you couldn't retro fit some radios and nav units due to the electrics not being compatible without further mods.
Morty and SteveP will know, failing that have a look in the relevant sections on StevePs mk5 forum which has everything you always wanted to know about every retro fit ever thought of.
Incidentally I had factory sat nav in my Polo GTI 1.8t however many years ago, and even that had issues with battery drain.
