My daughter just got a new TomTom VIA 1505 TM.Now she doesnt have a computer ,so I'll be doing her updates ans stuff on mine.My question is since I have the XL350 TM and we both have lifetime maps,will it mess my map updates on my TomTom home if I also connect hers to it orwill it be alright and it'll know which update to put where.Sorry this sounds stupid,but iam just wondering if both of our tom toms will be alright from the one home page.I hope Iam explaning this right.Thanks
